Lab Solution

Task 1

Configure R1, R3 to exchange RIP updates only when there is a topology change (on demand circuit).

R1 Configuration:

!

interface Serial0/1
 ip address 10.1.13.1 255.255.255.0
 ip rip triggered
 serial restart-delay 0

!

R3 Configuration:

!

interface Serial0/1
 ip address 10.1.13.3 255.255.255.0
 ip rip triggered
 serial restart-delay 0

!

Verification:

Pic. 2 - RIP Updates on R3.

Notice!
R3 is NOT sending updates out Serial0/1 anymore.

Pic. 3 - RIP Details on R3.

Notice!

S0/1 interface is enabled for triggered updates now. Also R1's Serial0/1 interface has the same setting. The result is that the last update exceeds the maximum 30 seconds but the entry is still valid.

Pic. 4 - R3's Routing Table.

Notice!

The current time of the last update from R1 is 09:19 minutes. Still, the entries are valid.
