Does anyone know if there is an "object tracking" sort of feature in OSPF where a default route can be stop being advertised based on a route disappearing from the routing table?
I've checked the IOS SLA and it just seems like that can only install a floating route if a tracked object disappears.... I didn't see where that feature worked to take a route out of OSPF.
Lisa, by remarkable coincidence, I was playing with this feature in the lab just today.
ip prefix-list route-condition permit 10.0.0.0/8
match ip address prefix route-condition
router ospf 1
originate default-information route-map mycondition
That would generate a default route provided 10.0.0.0/8 was in the routing table.
