Hi all.
Here is the topology.
R3------ospf-----R1
 
R3 has three loopback interfaces.
Lo 1: 130.10.31.1/27
Lo 2: 130.10.31.33/27
Lo 3: 33.33.33.3/24 (BGP 100 interface )
 
First, what I did was that I redistributed lo 1 and 2 into OSPF using
"redistribute connected"
It was successfully redistributed.
Now secondly, if I redistribute lo 3 interface (BGP Interface) into OSPF, it
doesn't happen.
 
Here is the config of R3
router ospf 1
router-id 3.3.3.3
log-adjacency-changes
summary-address 130.10.31.0 255.255.255.0
redistribute connected subnets route-map c2o
redistribute bgp 100 subnets
network 130.10.30.0 0.0.0.255 area 3
network 130.10.134.0 0.0.0.255 area 0
!
router bgp 100
bgp router-id 3.3.3.3
bgp cluster-id 2181701409
bgp log-neighbor-changes
network 33.33.33.0 mask 255.255.255.0
neighbor 130.10.134.1 remote-as 100
!
access-list 31 permit 130.10.31.0 0.0.0.255
 
route-map c2o permit 10
match ip address 31
 
I think the problem is lo 3 is treated as the connected network and it is
blocked by the route-map.
 
Is there any way to get around with this?
 
Thanks,
 
JP
