Guys we have two redundant routers in WAN which is config with BGP with service provider....the LAN side wee have OSPF configured.
Now we are agreegating BGP as we are getting heaps of OSPF routes with /24 from core......
The situation is that we have to config loopack 0 (as it sstandard on WAN routers for remote management) The problem is that we are aggregating
just exaple 192.168.0.0/16 and the loopback is 192.168.2.2/32 we are redistributing ospf directly into bgp with redistribute command as we are not using any network statement under BGP. Now i have added 192.168.2.2 mask 255.255.255.255 in BGP with network command as OSPF is not config on loopack. The probelm is that when we did failover testing by shutting the lan down still its advertising 192.168.0.0/16 network the reason being is that there is one specific route (the loop) in the routing table and its up so even the lan is down but loopback is up........so the traffic never takes the redundant link what is a solution for this as we cant use other IP for loopbacks.
