Objective Configure Static NAT and Dynamic NAT with Port Address Translation

Step 1 Basic Router Configuration • Erase each router’s configuration and reload. Configure each router with you Instructor’s

required basic configurations. • Configure and activate all interfaces according to the topology and the equipment you are using. • Configure a default route on GATEWAY pointing to ISP • Configure ISP with a static route pointing to the NAT pool for GATEWAY

Step 2 Configure Static NAT and Dynamic NAT with Port Address Translation • Configure GATEWAY to statically translate the Inside Web Server address (10.0.1.1) to the first

address in the NAT pool • Using the rest of the NAT pool, configure GATEWAY to dynamically translate hosts that belong

to the 10.0.0.0/24 network. Make sure you enable PAT so that more that one host can share the same IP address.

• Designate how interfaces will participate in the NAT process

Step 3 Verify and Monitor NAT Configuration • From GATEWAY, issue two extended pings. The first ping should use the address 10.0.0.1 as

the source and the second ping should use 10.0.1.1 as the source. Both pings should work. If not, troubleshoot your configurations.

• Use the NAT show commands to view translations and statistics.

Objective • Prior Skills: Demonstrate use of dynamic routing, static routing, and advertising a default route.

• New Skills: Demonstrate proper configuration of NAT and DHCP.

Scenario A Dr. Sue Menow has hired you to set up her network of three clinics: Central Clinic (RTA), East Clinic (RTB), and West Clinic (RTC). She has bought three routers and has contracted with a service provider for three T1 links. She wants you to configure her routers so that the hosts at the East and West Clinics have access to the Internet through the Central Clinic’s router.


Design Considerations You can use any four routers at your disposal. RTA is shown to be attached through a LAN interface to ISP. Although this is not realistic (you would use a WAN interface), the design allows you to use any routers from the CCNA Lab Bundle. If you have access to a 2600 router with four serial interfaces, use this router for RTA. Also, the LAN attached to RTA can be simulated with a loopback interface. However, this could be an actual LAN if the router you use has two LAN interfaces.

Implementation Requirements • Cable the lab with available equipment in the configuration shown in the graphic. Label the

graphic with the appropriate interface names (such as S0, S0/0, E0, Fa0, etc.). Label serial interfaces with the appropriate DTE or DCE designation.

• Design an appropriate VLSM addressing scheme using the following method to assign subnets and interface addresses.

o 1st Level of subnetting: assign subnet zero to the LAN off of RTB

o 2nd Level of subnetting: assign subnet zero to the LAN off of RTC

o 3rd Level of subnetting: assign subnet zero to the LAN off of RTA

o 4th Level of subnetting: assign subnet zero to the link between RTA and RTB; assign subnet one to the link between RTA and RTC.

o For LAN interfaces, use the first available host address in the assigned subnet.

o For WAN interfaces, assign the first available host address to RTA. This requirement includes the “WAN” link RTA shares with ISP.

• Fill in the table below the topology with your addressing design and label the topology with the assigned subnets. Helpful Hint: Also label the interfaces with the last octet of the interface’s IP address.

• Erase each router’s configuration and reload. Configure each router with basic configurations.

o Hostnames

o Passwords

o Host Table

o Console Line and Telnet Lines

o Interface Addresses

• Configure RIPv2 inside the network. DO NOT configure RIPv2 between RTA and ISP. Helpful Hint: At this point, RTB should be able to ping RTC.

• Configure NAT on RTA.

• Configure DHCP on RTB for its LAN and on RTC for its LAN. For each DHCP configuration, exclude the first three addresses from the DHCP pool.

• On ISP, configure a static route to the enterprise. Helpful Hint: The static route points to the enterprise’s NAT pool—not the inside private addresses.

• On RTA, configure a default route to ISP. To distribute the default route to RTB and RTC, you must enter the following command within the RTA’s RIP routing process: RTA(config-router)#default-information originate


Implementation Verification Steps • Capture output from DOS showing that both workstations received an IP address and can ping

the Simulated Web Server. This will verify your DHCP, NAT and default routing configurations.

• Capture show commands verifying DHCP and NAT configuration. Helpful Hint: NAT times out entries quickly, so have the workstations ping the Simulated Web Server continuously until you get the show output for NAT. To do this, use the following example: C:\ping 147.32.15.35 –n 1000

This will ping the Simulated Web Server 1000 times. You can stop the ping with the Ctrl + C key combination.

• Capture the routing tables on all four routers.

• Capture the running configuration on all four routers.

• Clean up your verification captures and make appropriate notations.

Step 3 HQ Basic Configurations • Configure HQ with basic router configurations including PPP encapsulation on the WAN link

• Bring up both interfaces.

• DO NOT configure CHAP yet.

• Make sure HQ can ping ISP’s serial interface. If not, you can troubleshoot using the debug ppp negotiation command. HQ#ping 200.20.2.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 200.20.2.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/6/8 ms HQ#

Step 4 Configure CHAP Authentication • Using the password isplink, configure CHAP as the Authentication protocol on both ISP and

HQ.

o The link between HQ and ISP will go down until you configure both sides of the link correctly.

• Make sure HQ can ping ISP’s serial interface. If not, you can troubleshoot using the debug ppp authentication command.

o Remember: usernames must match the hostname of the remote router and passwords are case sensitive.

Step 5 Configure the DHCP Server • Configure HQ as the DHCP Server for the 192.168.1.0/24 network

o Exclude the first three IP addresses from the DHCP pool

• Verify that the workstation dynamically obtained the correct configuration information and can ping its default gateway. If not, troubleshoot. C:\>ipconfig

Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.1.4 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1

Step 6 Configure the NAT Server • Configure HQ with a NAT server to dynamically assign global outside IP addresses from the

NAT pool 137.38.39.40/29 to local inside packets attempting to access the Internet. Any packet with an IP address from the 192.168.1.0/24 network will be translated.

o Make sure you use PAT so that more than one user can be translated to use the same global outside IP address.

Step 7 Verify Connectivity • On the workstation, open up a web browser window. Type the IP address 145.46.47.48 in the

Address field and hit the Enter key.

o If a password authentication dialog box appears, then you have full connectivity. Type cisco as the usename and class as the password. The web page for the ISP router should appear.

Step 5 Add Internet connectivity, configure NAT, and configure default routing a. Configure ISP with basic router configurations. Add the loopback interface and configure the serial

interface.

b. DO NOT CONFIGURE ANY ROUTING ON ISP!! No static or dynamic routing is needed.

c. Verify that ISP can ping RTA

d. Configure PAT (NAT overload) on RTA. Since you have not been assigned a pool of addresses, RTA the real IP address you assigned it from the 200.20.2.0/30 network.

e. Configure RTA with a default route pointing to ISP. Use the default-information originate command within the OSPF routing process on RTA to propagate the default route to RTB and RTC.

Step 4 Configure Easy IP on HQ for LANs attached to HQ, SALES, and MAIN a. The HQ router will server as the DHCP server for LANs attached to HQ, SALES, and MAIN.

Configure all three DHCP pools on HQ. Add corpnet.com as the domain name.

b. Excluded the first three address in each DHCP so that these addresses will not be dynamically assigned to hosts.

c. Configure SALES and MAIN with a helper address so that DCHP broadcasts will be forwarded to HQ.

d. Verify workstations attached to HQ, MAIN and SALES dynamically received correct IP configurations. The IP address assigned may be different than below, but no address below a .4 address should be assigned.

================= HQ workstation ================= Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : corpnet.com IP Address. . . . . . . . . . . . : 172.16.0.4 Subnet Mask . . . . . . . . . . . : 255.255.252.0 Default Gateway . . . . . . . . . : 172.16.0.1 ================= MAIN workstation ================= Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : corpnet.com IP Address. . . . . . . . . . . . : 172.16.4.4 Subnet Mask . . . . . . . . . . . : 255.255.254.0 Default Gateway . . . . . . . . . : 172.16.4.1 ================= SALES workstation ================= Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : corpnet.com IP Address. . . . . . . . . . . . : 172.16.6.4 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 172.16.6.1


Step 5 ISDN with Dialer Profiles, PPP with CHAP, and DHCP on REMOTE a. The ISDN link between SALES and REMOTE should be configured with dialer profiles using the

following requirements.

o Permit any IP traffic to dial the ISDN link

o PPP encapsulation with CHAP authentication

o Load threshold should be set at 50%

o Idle timeout should be 60 seconds and fast idle 15 seconds

b. Configure SALES with a static route pointing to the LAN attached to REMOTE. . Note: If you use the “outbound interface” argument, it must be set to the dialer interface.

c. Redistribute the SALES static route in the EIGRP routing process. Disable EIGRP hello messages out the dialer interface on SALES with the passive-interface command so that EIGRP will not call the ISDN link.

SALES(config)#router eigrp 100 SALES(config-router)#redistribute static SALES(config-router)#passive-interface Dialer0

d. Configure REMOTE with a default route pointing to SALES. Note: If you use the “outbound interface” argument, it must be set to the dialer interface.

e. Configure REMOTE with Easy IP, excluding the first three IP addresses and setting corpnet.com as the domain name

f. Verify a workstation attached REMOTE dynamically received that correct IP address configuration. IP address assigned may be different than below, but no address below a .4 address should be assigned.

=================== REMOTE workstation =================== Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : corpnet.com IP Address. . . . . . . . . . . . : 172.16.7.4 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 172.16.7.1

g. Verify that the REMOTE workstation can ping the web server at 145.46.47.48. C:\>ping 145.46.47.48 Pinging 145.46.47.48 with 32 bytes of data: Reply from 145.46.47.48: bytes=32 time=1ms TTL=255 Reply from 145.46.47.48: bytes=32 time=1ms TTL=255 Reply from 145.46.47.48: bytes=32 time=2ms TTL=255 Reply from 145.46.47.48: bytes=32 time=1ms TTL=255 Ping statistics for 145.46.47.48: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 1ms, Maximum = 2ms, Average = 1ms


CCNA4 Module 5 Challenge Lab #1: Frame Relay Full Mesh

Objective Configure and Verify Frame Relay in a Full Mesh Topology

Optional Objectives at Instructor’s Discretion:

• Configure EIGRP to advertise summary routes for simulated LANs

• Add a ISP router and configure default routing, PPP with CHAP and NAT overload

• Configure HQ as the DHCP server for LANs attached to HQ, MAIN, and SALES

• Add a REMOTE router over an ISDN link using PPP with CHAP

Step 1 Cable and Label the Topology Connect all the necessary equipment to complete the lab. Connect additional routers as needed for the optional portions of the lab.


Step 2 Configure the Core Topology with Frame Relay and Routing Configuration Configure all routers with basic configurations including instructor required configurations and all IP addresses. You may want to skip configuring Loopbacks until Step 3.

Configure Frame Relay encapsulation on serial interfaces. After allowing sufficient time to pass (sometimes up to 2 minutes), the three routers should have complete Frame Relay maps HQ#show frame-relay map Serial0 (up): ip 10.0.0.1 dlci 16(0x10,0x400), dynamic, broadcast, status defined, active Serial0 (up): ip 10.0.0.2 dlci 17(0x11,0x410), dynamic, broadcast, status defined, active

If you are having difficulty obtaining the above output, use show frame-relay pvc to verify that both PVCs are actually listed. You may have a physical layer problem.

Once Frame Relay is up dynamically, configure static maps with the frame-relay map command and configure the LMI type to be ansi.

Configure EIGRP as the routing protocol. Make sure to turn off automatic summarization. Without the Loopbacks configured, HQ’s routing table should look like the following: HQ#show ip route <output omitted> Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 13 subnets, 6 masks D 10.2.0.0/24 [90/2195456] via 10.0.0.2, 06:39:40, Serial0 C 10.3.0.0/24 is directly connected, Ethernet0 C 10.0.0.0/29 is directly connected, Serial0 D 10.1.0.0/24 [90/2195456] via 10.0.0.1, 06:37:52, Serial0

Step 3 Configure EIGRP Summary Routes (Optional) Configure the Loopbacks shown on the topology. HQ’s routing table then should look like the one below. MAIN and SALES will have similarly large tables. HQ#show ip route <output omitted> Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 17 subnets, 7 masks D 10.0.0.8/30 [90/41024000] via 10.0.0.1, 00:00:54, Serial0 D 10.2.0.0/24 [90/2195456] via 10.0.0.2, 00:00:54, Serial0 C 10.3.0.0/24 is directly connected, Ethernet0 C 10.0.0.0/29 is directly connected, Serial0 D 10.1.0.0/24 [90/2195456] via 10.0.0.1, 00:00:54, Serial0 D 10.24.0.0/14 [90/2297856] via 10.0.0.2, 00:00:55, Serial0 D 10.28.0.0/14 [90/2297856] via 10.0.0.2, 00:00:55, Serial0 D 10.16.0.0/14 [90/2297856] via 10.0.0.2, 00:00:55, Serial0 D 10.20.0.0/14 [90/2297856] via 10.0.0.2, 00:00:55, Serial0 D 10.40.0.0/13 [90/2297856] via 10.0.0.1, 00:00:55, Serial0 D 10.32.0.0/13 [90/2297856] via 10.0.0.1, 00:00:57, Serial0 D 10.56.0.0/13 [90/2297856] via 10.0.0.1, 00:00:57, Serial0 D 10.48.0.0/13 [90/2297856] via 10.0.0.1, 00:00:57, Serial0 C 10.64.0.0/12 is directly connected, Loopback0 C 10.80.0.0/12 is directly connected, Loopback1 C 10.96.0.0/12 is directly connected, Loopback2 C 10.112.0.0/12 is directly connected, Loopback3


Configure HQ, MAIN and SALES each with an EIGRP summary route to advertise to the other two EIGRP neighbors. CCNA3 Module 3 can be helpful. After doing so, HQ’s routing table will look like the one below: HQ#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 12 subnets, 6 masks D 10.0.0.8/30 [90/41024000] via 10.0.0.1, 06:37:52, Serial0 D 10.2.0.0/24 [90/2195456] via 10.0.0.2, 06:39:40, Serial0 C 10.3.0.0/24 is directly connected, Ethernet0 C 10.0.0.0/29 is directly connected, Serial0 D 10.1.0.0/24 [90/2195456] via 10.0.0.1, 06:37:52, Serial0 D 10.16.0.0/12 [90/2297856] via 10.0.0.2, 06:39:41, Serial0 D 10.32.0.0/11 [90/2297856] via 10.0.0.1, 06:37:53, Serial0 D 10.64.0.0/10 is a summary, 06:41:56, Null0 C 10.64.0.0/12 is directly connected, Loopback0 C 10.80.0.0/12 is directly connected, Loopback1 C 10.96.0.0/12 is directly connected, Loopback2 C 10.112.0.0/12 is directly connected, Loopback3

Step 4 Add ISP Router, Configure PPP, NAT, and Default Routing (Optional) Add an ISP router to the topology and configure it according to the topology. The Web Server can be a Loopback interface. Configure PPP with CHAP across the link.

Configure NAT on HQ by overloading the interface IP address that belongs to the 2.0.0.0/30 network.

On HQ, add a default route pointing to ISP. Configure HQ to advertise the default route in its EIGRP routing process with the following commands:

HQ(config)#ip default-network 2.0.0.0 HQ(config)#router eigrp 100 HQ(config-route)#network 2.0.0.0

MAIN and SALES should both have a Gateway of Last Resort (a default router) and be able to ping the Web Server on ISP. SALES’s routing table should look like the following: SALES#show ip route <output omitted> * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is 10.0.0.3 to network 2.0.0.0 2.0.0.0/30 is subnetted, 1 subnets D* 2.0.0.0 [90/2681856] via 10.0.0.3, 01:39:41, Serial0 10.0.0.0/8 is variably subnetted, 13 subnets, 7 masks D 10.2.0.0/24 [90/2195456] via 10.0.0.2, 06:43:57, Serial0 D 10.3.0.0/24 [90/2195456] via 10.0.0.3, 01:10:51, Serial0 C 10.0.0.0/29 is directly connected, Serial0 C 10.1.0.0/24 is directly connected, Ethernet0 D 10.16.0.0/12 [90/2297856] via 10.0.0.2, 06:43:57, Serial0 C 10.40.0.0/13 is directly connected, Loopback1 D 10.32.0.0/11 is a summary, 06:47:39, Null0 C 10.32.0.0/13 is directly connected, Loopback0 C 10.56.0.0/13 is directly connected, Loopback3 C 10.48.0.0/13 is directly connected, Loopback2 D 10.64.0.0/10 [90/2297856] via 10.0.0.3, 06:44:27, Serial0


Step 5 Configure DHCP Server (Optional) Configure HQ as the DHCP server for LANs attached to HQ, MAIN, and SALES. Exclude the first three addresses from each pool.

Configure both MAIN and SALES to send DHCP requests to HQ

Step 6 Add a REMOTE router over an ISDN link Configure SALES and REMOTE with ISDN. Use either legacy DDR or dialer profiles.

Use PPP with CHAP as the encapsulation

Configure a default route pointing to SALES and configure SALES with a static route pointing to REMOTE’s LAN. Redistribute SALES’ static route in the EIGRP routing process with the redistribute static command.

CCNA4 Module 5 Challenge Lab #2: Frame Relay Subinterfaces

Objective Configure and Verify Frame Relay in a Full Mesh Topology

Optional Objectives at Instructor’s Discretion:

• Add a ISP router and configure default routing, PPP with CHAP and NAT overload

• Configure each router to be its own DHCP server.

• Add a REMOTE router over an ISDN link using PPP with CHAP

Step 1 Cable and Label the Topology Connect all the necessary equipment to complete the lab. Connect additional routers as needed for the optional portions of the lab.


Step 2 Configure the Core Topology with Frame Relay and Routing Configuration Configure all routers with basic configurations including instructor required configurations and all IP addresses. You may want to skip configuring Loopbacks until Step 3.

Configure Frame Relay encapsulation using subinterfaces. After allowing sufficient time to pass (sometimes up to 2 minutes), the three routers should have complete Frame Relay maps HQ#show frame-relay map Serial0/0.18 (up): point-to-point dlci, dlci 18(0x12,0x420), broadcast status defined, active Serial0/0.17 (up): point-to-point dlci, dlci 17(0x11,0x410), broadcast status defined, active

If you are having difficulty obtaining the above output, use show frame-relay pvc to verify that both PVCs are actually listed. You may have a physical layer problem.

Configure OSPF as the routing protocol. Make sure you only advertise those networks that are in the shaded OSPF area. Do not advertise the link between HQ and ISP or the link between SALES and REMOTE. Without an ISP and REMOTE router yet, HQ’s routing table should look like the following: HQ#show ip route <output omitted> Gateway of last resort is not set 10.0.0.0/8 is variably subnetted, 8 subnets, 3 masks C 10.10.0.1/32 is directly connected, Loopback0 C 10.0.0.8/30 is directly connected, Serial0/0.18 O 10.2.0.0/24 [110/782] via 10.0.0.2, 00:17:59, Serial0/0.17 O 10.3.0.0/24 [110/782] via 10.0.0.9, 00:17:59, Serial0/0.18 C 10.0.0.0/30 is directly connected, Serial0/0.17 C 10.1.0.0/24 is directly connected, FastEthernet0/0 O 10.0.0.4/30 [110/845] via 10.0.0.2, 00:17:59, Serial0/0.17

Step 3 Add ISP Router, Configure PPP, NAT, and Default Routing (Optional) Add an ISP router to the topology and configure it according to the topology. The Web Server can be a Loopback interface. Configure PPP with CHAP across the link. Make sure that ISP has a static route pointing to the NAT pool, not the 10.0.0.0/8 address space.

Configure NAT on HQ using the assigned pool shown in the topology. The first address in the pool, 3.0.0.0, will be statically assigned to the Simulated Inside Web Server at 10.10.0.1. The rest of the addresses in the NAT pool can be dynamically assigned to other hosts within the 10.0.0.0/8 address space.

On HQ, add a default route pointing to ISP. Configure HQ to advertise the default route in its OSPF routing by using the default-information originate command

MAIN and SALES should both have a Gateway of Last Resort (a default router) and be able to ping the Web Server on ISP. SALES’s routing table should look like the following: SALES#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR P - periodic downloaded static route Gateway of last resort is 10.0.0.10 to network 0.0.0.0 10.0.0.0/8 is variably subnetted, 10 subnets, 3 masks O 10.10.0.1/32 [110/782] via 10.0.0.10, 00:21:25, Serial0/0.16 C 10.0.0.8/30 is directly connected, Serial0/0.16 C 10.0.0.14/32 is directly connected, Dialer0 C 10.0.0.12/30 is directly connected, Dialer0 O 10.2.0.0/24 [110/782] via 10.0.0.5, 00:21:25, Serial0/0.17 C 10.3.0.0/24 is directly connected, FastEthernet0/0 O 10.0.0.0/30 [110/845] via 10.0.0.5, 00:21:25, Serial0/0.17

Step 4 Configure DHCP Server (Optional) Configure each router to be its own DHCP server. Exclude the first three addresses from each pool.

Step 5 Add a REMOTE router over an ISDN link Configure SALES and REMOTE with ISDN using dialer profiles.

Use PPP with CHAP as the encapsulation

Configure a default route pointing to SALES and configure SALES with a static route pointing to REMOTE’s LAN. Redistribute SALES’ static route in the OSPF routing process with the redistribute static subnets command. Otherwise, HQ and MAIN will not learn about the LAN on REMOTE.
