RIP - Suppressing Default information Routing

Tasks:
Configure routers so that R2 will be the default router for whole network and it will originate default information to whole network but only on speciified interfaces.

In this case we wanna send default network to R1 but not to R3.

!R1 configuration
interface Loopback0
 ip address 10.1.1.1 255.0.0.0
!
interface Serial0/0
 ip address 1.1.1.1 255.0.0.0
no shut
!
router rip
 version 2
 network 1.0.0.0
 network 10.0.0.0


!R2 configuration
interface Serial0/0
 ip address 1.1.1.2 255.0.0.0
 no shut
!
interface Serial0/1
 ip address 2.2.2.1 255.0.0.0
no shut
!
router rip
 version 2
 network 1.0.0.0
 network 2.0.0.0
 default-information originate route-map stop-default



route-map stop-default
 set interface Serial0/1



!R3 configuration
interface Serial0/0
 ip address 2.2.2.2 255.0.0.0
 no shut
!
router rip
 version 2
 network 2.0.0.0

Explanation


























Applying route map to send default information originate. Now default information will only be sent to interface specified in route map

Creating route map
setting interface in the route map
