Lab 6.2.2 EIGRP and Backup Routes

Objective:

Enable EIGRP routing protocol with backup routes.

(Note: Erase "Router A" and "Router B" before beginning)

Scenario:

The Lubbock ISP has purchased more RAM for their core routers. They want you to setup EIGRP on their two core routers and configure a backup link. Tasks:

From the "Router A" console

  1. Cable the lab as shown above.
  2. Issue the following commands:
  • router-a(config)#interface fastethernet 0/0
  • router-a(config-if)#ip address 206.202.16.1 255.255.255.0
  • router-a(config-if)#no shutdown
  • router-a(config-if)#interface serial 0/0
  • router-a(config-if)#ip address 206.202.17.1 255.255.255.0
  • router-a(config-if)#clockrate 56000
  • router-a(config)#router eigrp 44
  • router-a(config-router)#network 206.202.16.0
  • router-a(config-router)#network 206.202.17.0
  • router-a(config-router)#^Z

From the "Router B" console

  1. Issue the following commands:
  • router-b(config)#interface fastethernet 0/0
  • router-b(config-if)#ip address 206.202.16.2 255.255.255.0
  • router-b(config-if)#no shutdown
  • router-b(config)#interface serial 0/0
  • router-b(config-if)#ip address 192.168.0.1 255.255.255.0
  • router-b(config-if)#clockrate 56000
  • router-b(config-if)#no shutdown
  • router-b(config)#router eigrp 44
  • router-b(config-router)#network 206.202.16.0
  • router-b(config-router)#network 192.168.0.0
  • router-b(config-router)#^Z

From the "Router D" console

  1. Issue the following commands:
  • router-d(config)#interface fastethernet 0/1
  • router-d(config-if)#ip address 206.202.18.1 255.255.255.0
  • router-d(config-if)#no shutdown
  • router-d(config-if)#interface serial 0/0
  • router-d(config-if)#ip address 206.202.17.2 255.255.255.0
  • router-d(config)#router eigrp 44
  • router-d(config-router)#network 206.202.18.0
  • router-d(config-router)#network 206.202.17.0
  • router-d(config-router)#^Z

From the "Router B" console

  1. Enter show ip eigrp neighbors and show ip eigrp topology all-links

Are there any successors for the 206.202.17.0 network ?

  1. Enter show ip eigrp interfaces

How many interfaces

  1. Enter show ip route command and list the routes below:

  1. Enter trace 206.202.18.1 and list below your findings:

  1. Issue the following commands on "Router B":
  • router-b(config)#interface serial 0/0
  • router-b(config-if)#bandwidth 56
  • router-b(config-if)#^Z
  1. Enter show ip route command and list the routes below:

  1. Enter trace 206.202.18.1 and list below your findings:

  1. Enter show ip eigrp topology 206.202.18.0 and list below your findings:

  1. Issue the command debug eigrp fsm and then remove the FastEthernet cable from the FastEthernet 0/0 interface on "Router A"

  1. Enter ping 206.202.18.1 and show ip route. List your findings below:
