Hi - I'm working on a design with two different ISP providers. I'm running BGP with the providers and advertising my company owned address block. AS-prepending on one side. That's working fine.
I'm running OSPF in the inside with a Check Point firewall cluster. The two ISP routers are only sending the default route to the firewalls.
router ospf 1
router ospf 1
default-information originate metric 155
Both Routers and the Firewalls are all on the same segment. I can see neighbor relationships, LSA database etc.
I'm expecting that when Router-A (primary) goes down, the route to Router-B comes in. That seems to be working fine. Now when Router-A comes back I'm expecting the firewall to start using the route to Router-A again but its not. Am I miss-interpreting this behavior?
This seems like such a basic design/config - I baffled as to why its not working. Do I need to adjust or tweak DR/BDR or anything of that nature.
PS - I have a TAC case open with Check Point but I just wanted to sanity check this with the group here.
