OSPF route expired? VRRP state changed....

Hello,

 

I have a problem. The VRRP state changed every 29 hours, see below for the loggin. I defined a tracking command to check if there is a route.

Tracking command: track 2 ip route 10.240.4.0 255.255.254.0 reachability

This route is learned bij OSPF:

O        10.240.4.0/23 [110/3] via 10.31.171.1, 06:08:28, GigabitEthernet0/0
 

What can be the problem? Are OSPF routes expired after 29 hours? Is the tracking mechanisme not the right one?
 

VRRP logging:

*Sep 17 08:49:21.488: %VRRP-6-STATECHANGE: Gi0/1 Grp 11 state Backup -> Master

*Sep 17 08:49:21.492: %VRRP-6-STATECHANGE: Gi0/1 Grp 11 state Master -> Backup

Well the VRRP with tracking

Well the VRRP with tracking is doing what it is supposed to do, that is, it changes state when it loses that particular route so I see no issues there. OSPF should refresh its LSA every 30 minutes which could be the issue you are facing. Check out the link below:
