Configuration rules:

- Application IP addresses are tied toapplication RG and configured as loopback

addresses

- Internal network interface and gatewayaddresses are configured at mcRNCcommissioning phase. The related redundantcysolution static route entries should appear inthe system automatically.

- The interface addresses for inter nodeforwarding are needed for each CFPU andEIPU.

- The gateway addresses are configured for

each User plane and Iub control plane recoverygroups based on which the active RU of the RGcan be reached from any other node notrunning the given RG.

Static routes:

Ingress:

- Static route is configured in each EIPU inBCN1&2 pointing to the redundant EIPUinternal address

- 10.1.0.1 -> cfeigw EIPU-x

Egress:

- Primary static route is configured towards theRouter connected to the EIPU.

- The secondary static route is configured withlower preference via the other EIPU within thesame BCN module.

mcRNC Interface

mcRNC has a variety of interface. We should know them, will

help us to undersatnd the configuration.

1.Physical interace

Eg:sfp7~~~~sfp16





mcRNC Interface

2.Logical interface, mapping physical interface

Eg:

add networking ether /EIPU-0 iface ethsfp7 port sfp7

3.Vlan interfaceEg:

add networking instance vrf1cp vlan /EIPU-0 realifaceethsfp7 vid 350 vlaniface iucscp_r1





mcRNC configure SCLI

1. Configure Interface

• Logical interface,mapping to physical

//add networking ether /EIPU-0 iface ethsfp7 port sfp7

• Vlan interface for IuCP and forward

//add networking instance vrf1cp vlan /EIPU-0 realiface ethsfp7 vid350 vlaniface iucscp_r1

//add networking instance vrf1cp vlan /EIPU-0 realiface ethsfp7 vid359 vlaniface eipu0sfp7

2. Configure IP

• IuCP and forward IP

//add networking instance vrf1cp address dedicated /EIPU-0 ifaceiucscp_r1 ip-address 192.160.64.1/28 user /SS7SGU

//add networking instance vrf1cp address dedicated /EIPU-0 ifaceeipu0sfp7 ip-address 192.160.100.2/24






2. Configure IP

• All UP and IUBCP IP

//add networking instance vrf1up address dedicated /QNUP-0 ifacelo11 ip-address 192.160.65.1/32 role iucsup

//add networking instance vrf1cp address dedicated /QNIUB-0 ifacelo10 ip-address 192.160.0.1/32 role iub

3. Configure route

•For external

//set routing instance vrf1cp node EIPU-1 static-route

192.160.16.0/22 nexthop gateway address 192.160.104.1 priority 1 on•For internal

//set routing instance vrf1cp node EIPU-1 static-route192.160.16.0/22 nexthop gateway address 169.254.10.6 priority 8 on






4. IP base route

//add ipbr ipbr-id 1 committed-bandwidth 100000committed-dcn-bandwidth 0 committed-sig-bandwidth 0 ipbr-name WBTS-1 route-bandwidth 300000

5. IP RO

//add ipro ipbr-id 1 ip-address 192.160.1.1 iface lo10owner /QNUP-0 vrf-id 10






6. Iubsnt

//add iubsnt local-subnet-id 1 net-address 192.160.0.1/26 vrf-id 10

7. SS7





Introduce Pettester

Here we mainly introduceconfig.ini.
