We have 2 core routers running HSRP with some static routes being advertized to the WAN. Router 1 is the active router, router 2 the standby. Show standby verifies this.
Just looking at one instance of the observed phenominon, both core routers have a static route for a subnet to another network device, the route never changes.
2 routers have interfaces on a common subnet with the core routers and are getting getting route updates for this particular route. Router 3 is getting updated every couple of days from router 2 and router 4 is getting updated every month from router 1. Both routes are pointing to the standby HSRP router.
Why is the route being updated when it isn't changing and why is is pointing to the wrong router in the HSRP?
