1. Enable debugging on each router and show the output:

2. Show ip route. Discuss the output?

We can see all four loopbacks in 9R4 routing table.

3. Show ip route < loopback of YR4/XR4> on YR4/XR4. Discuss the output?It displays the route to 172.16.3.3 from 9R4 i.e. 172.16.2.2

4. Show mpls traffic-eng tunnels. Discuss the output?

This command displays the explicit route followed and information about the tunnel running from 172.16.1.1 to 172.16.4.4.

5. Show mpls traffic-eng tunnels brief. Discuss the output.

It shows that LSP tunnels are running from 9R1 to 10R1

6. Ping from 10R2 to 9R2

How will you describe unequal cost load balancing from this lab?

Unequal cost load balancing in MPLS is done by using 16 hash buckets for next-hop which are shared in rough rough propostion to configured tunnel bandwidth or load-share value.

10. Capture the output from the sniffer and comment on them?

Path message is contained in RSVP message. The explicit route followed is 192.168.14.4 - 192.168.141.1 - 172.16.4.4 to destination 172.16.1.1
