Re: VRRP interface tracking

mahesh18 · ‎02-09-2013

Hi all,

I config 2691 as Master for VRRP and it was tracking int fa0/0.

I shutdown the interface fa0/0 and

2691 int fa1/1 was changed from master to backup.

2691Router# sh vrrp

FastEthernet1/1 - Group 30

State is Backup

Virtual IP address is 192.168.7.1

Virtual MAC address is 0000.5e00.011e

Advertisement interval is 0.100 sec

Preemption enabled, delay min 60 secs

Priority is 90

Track object 1 state Down decrement 10

Master Router is 192.168.7.2, priority is 100

Master Advertisement interval is 1.000 sec

Master Down interval is 0.909 sec (expires in 0.385 sec)

Then i checked the logs on the router which are below

Feb 9 11:42:58.652 MST: %VRRP-6-STATECHANGE: Fa1/1 Grp 30 state Backup -> Master

Feb 9 11:42:58.688 MST: %VRRP-6-STATECHANGE: Fa1/1 Grp 30 state Master -> Backup

Feb 9 11:43:20.273 MST: %VRRP-6-STATECHANGE: Fa1/1 Grp 30 state Master -> Backup

Need to know when int fa1/1 has become the backup then why it is bouncing between backup and master?

Thanks

Hi Mahesh,

I didnt find any issue on my device with this configuration.

Let me know how is your setup?

R u testing this on GNS? If yes do provide me the GNS file so that I test and get back to you with the result.

If its on live then provide me the network diagram and config from all the devices.

Regards
