Lab Solution

Task 1

Configure R1, R2 and R4 so they send RIP advertisement using unicast instead of multicast on the LAN.

R1 Configuration:

!

router rip
 version 2
 passive-interface FastEthernet1/0
 passive-interface Loopback0
 network 10.0.0.0
 network 172.16.0.0
 neighbor 10.1.124.4
 neighbor 10.1.124.2
 no auto-summary

!

R2 Configuration:

!

router rip
 version 2
 passive-interface FastEthernet1/0
 passive-interface Loopback0
 network 10.0.0.0
 network 172.16.0.0
 neighbor 10.1.124.4
 neighbor 10.1.124.1
 no auto-summary

!

R4 Configuration:

!

router rip
 version 2
 passive-interface FastEthernet1/0
 passive-interface Loopback0
 passive-interface Loopback1
 network 10.0.0.0
 network 172.16.0.0
 neighbor 10.1.124.2
 neighbor 10.1.124.1
 no auto-summary

!

Note!

The 'neighbor' command turns on unicast for RIP updates. However, a router still uses multicast (224.0.0.9) as well. To turn off multicast RIP updates completely, the 'passive-interface' command is required.
