Configure VRRP Advertisement Interval

See the first figure in VRRP Topology for the topology in this example. You can configure VRRP master router to send an advertisement packet at regular intervals to convey to the backup routers that the master is alive. By default, this interval is 1 second. You can configure this value in the range 1 to 255. In this example, you set the advertisement interval to 5 seconds on VLAN 2.

1. In both switches, configure the advertisement interval.

   SEFOS# configure terminal
   SEFOS(config)# router vrrp
   SEFOS(config-vrrp)# interface vlan 2
   SEFOS(config-vrrp-if)# vrrp 1 timer 5
   SEFOS(config-vrrp-if)# end

2. View the advertisement timer interval configured in switch 1.

   SEFOS# show vrrp interface vlan 2 detail
   vlan2  - vrID 1
   ---------------
   State is Master
   Virtual IP address is 12.0.0.5
   Virtual MAC address is 00:00:5e:00:01:01
   Master router is 12.0.0.5
   Associated IpAddresses :
   ----------------------
   12.0.0.5
   12.0.0.6
   Advertise time is 5 secs
   Current priority is 200
   Configured priority is 200, may preempt
   Configured Authentication
   Authentication key is text1
   Accept Mode Disabled
