Suppressing RIP route advertisements on VRRP backup devices

RIP route advertisement suppression can be enabled on VRRP backup devices to prevent other VRRP devices from learning multiple paths for a backed-up interface.

A VRRP or VRRP-E session with master and backup devices must be configured and running.

Normally, a VRRP or VRRP-E backup includes route information for the virtual IP address (the backed-up interface) in RIP advertisements. As a result, other devices receive multiple paths for the backed-up interface and might sometimes unsuccessfully use the path to the backup device rather than the path to the master device.

You can prevent the backups from advertising route information for the backed-up interface by enabling suppression of the advertisements.

NOTE
The command syntax is the same for VRRP and VRRP-E.
  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enable RIP. 
    device(config)# router rip
  3. Suppress RIP route advertisements. 
    device(config-rip-router)# use-vrrp-path

The following example suppresses RIP advertisements for the backed-up interface. 

device# configure terminal
device(config)# router rip
device(config-rip-router)# use-vrrp-path
