[c-nsp] Help on redistribute OSPF/BGP

[Olivier CALVANO]

Hi

Thanks,

i have added this into my router:

router bgp xxxx
 address-family ipv4 vrf MYVRF
  redistribute connected
  redistribute static
  redistribute ospf 1 vrf MYVRF match nssa-external 1 nssa-external 2
  no synchronization
 exit-address-family

and now, i see into my BGP the two prefixe:

7301#sh ip route vrf MYVRF ospf

Routing Table: MYVRF

     172.16.0.0/16 is variably subnetted, 17 subnets, 2 masks
O N1    172.16.7.29/32
           [110/40] via 172.16.11.94, 01:37:04, GigabitEthernet0/1.713
O N1    172.16.7.30/32
           [110/40] via 172.16.1.94, 01:38:42, GigabitEthernet0/1.713

on a other router of the MPLS IP VPN:

7204#sh ip route vrf MYVRF | inc /32
B       172.16.7.29/32 [200/40] via xx.xx.xx.xx, 00:07:04
B       172.16.7.30/32 [200/40] via xx.xx.xx.xx, 00:07:04


but now i want sent the BGP routes into the OSPF, i have added:

router ospf 1 vrf MYVRF
 router-id 172.16.1.254
 log-adjacency-changes
 area 30 nssa no-redistribution
 redistribute bgp xxxx subnets



but that's don't sent BGP route to the neighbor ospf (or i don't have
the good command for see
what route are sent ;=>)
