Lab 7.1.3 Distribute List 

Objectives:

  • Use a distribute list to filter routes.

Scenario:

Router B learns about the 10.0.0.0 via EIGRP and advertises it the rest of the autonomous system. You want to stop the updates from the 10.0.0.0 network from being propagated beyond Router B.

Lab Task:

  1. Cable the lab and all interfaces as shown in the diagram. Don't forget the no shutdown command.
  2. Configure EIGRP routing on all the routers.

    Router-a(config)#router eigrp 192 
    Router-a(config-router)#network 192.168.13.0
    Router-a(config-router)#network 10.0.0.0

    Router-b(config)#router eigrp 192 
    Router-b(config-router)#network 192.168.10.0 Router-b(config-router)#network 192.168.12.0 Router-b(config-router)#network 192.168.13.0

    Router-c(config)#router eigrp 192 
    Router-c(config-router)#network 192.168.10.0 
    Router-c(config-router)# network 192.168.11.0

    Verify that EIGRP is configured correctly and all routes are seen.

  3. Verify that EIGRP is configured correctly and all routes are seen.
  4. Configure Router B with the following commands to create a distribute-list.

    Router-b(config)#access-list 1 deny 10.0.0.0 Router-b(config)#access-list 1 permit any 
    Router-b(config)#router eigrp 192 Router-b(config-router)#distribute-list 1 out serial0/0

  5. Issue the command show ip route on Router C to see if the 10.0.0.0 route is listed. EIGRP is very fast. Issue the command show ip route on Routers A and B to see if there are any changes?
  6. Configure Router C with a static route to the 10.0.0.0 network for network services with a routing protocol.

    Router-c(config)#ip route 10.0.0.0 255.0.0.0 192.168.10.1

  7. Issue the command show ip route on Router C to see if the static route is listed.
  8. Issue the commands ping 10.0.0.1 and trace 10.0.0.1 from Router C. Record your results below.
