nexus 7000 route redistribution

[whanson]

                   CAn anyone tell me why I am getting this attempting to redistribute bgp into ospf

router ospf 10
  router-id 11.11.11.11
  redistribute bgp 65019 route-map test

ospf: 10 [3710] (default) Processing external redistributed route 151.151.151.151/32
ospf: 10 [3710] (default)   redist default_metric is 1
ospf: 10 [3710] (default)     Redistribution policy match NOT setting the: is_l3vpn flag
ospf: 10 [3710] (default)     Redistribution policy match failed
ospf: 10 [3710] (default) Flushing ext route 151.151.151.151/32
ospf: 10 [3710] (default) Flushing NSSA route 151.151.151.151/32

the route-map simply allows   0.0.0.0/0

thx again

In a non-MPLS VPN scenario, iBGP is not redistributed to IGP by default.

•In an MPLS VPN scenario (route distinguisher configured under a VRF), iBGP is redistributed to IGP by default.

You can use route maps to override the default behavior in both scenarios, but be careful when doing so as incorrect use of route maps can result in network loops. The following examples show how to use route maps to change the default behavior.

You can chnage the default behavior for scenario 1 by modifying the route map as follows:

route-map foo permit 10 

   match route-type internal 

router ospf 1 

   redistribute bgp 100 route-map foo

This obscure "match route-type internal" fixed a redisitribution issue between BGP and OSPF in one of our Nexus.
