Hi Experts,
Hope you can help.
I am stuck in a situation. I am trying to leak OSPF connected and IA learned routes to VRF routing table. VRF is in MP-BGP address family named "VPN-NETWORKS" on WS-6509 IOS 15.1.2 SY5.
Following is the config :
conf t
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!! Leaking from GLOBAL to NETWORKS !!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!
!
ip prefix-list GLOBAL-TO-VPN-NETWORKS seq 5 permit 192.101.254.0/24 ge 30
ip prefix-list GLOBAL-TO-VPN-NETWORKS seq 10 permit 172.18.255.0/24 ge 30
!
route-map IMPORT-GLOBAL-TO-VPN-NETWORKS permit 10
match ip address prefix-list GLOBAL-TO-VPN-NETWORKS
!
route-map IMPORT-GLOBAL-TO-VPN-NETWORKS deny 20
!
router bgp 64603
!
address-family ipv4 unicast
redistribute ospf 64603 route-map IMPORT-GLOBAL-TO-VPN-NETWORKS
vrf definition VPN-NETWORKS
rd 50:266
route-target export 50:64603
route-target import 50:64603
route-target import 1000:64603
!
address-family ipv4
import ipv4 unicast map IMPORT-GLOBAL-TO-VPN-NETWORKS
exit-address-family

This is alright for connected routes. What I am doing is redistributing ospf into bgp. The router on which I am doing this is a building router bsr and has two links to the Distribution router DR. Both links are pt-to-pt ospf links with cost of one. Now my problem is once the ospf learned remote routes are redistributed into bgp. When I do sh ip bgp , it does not give me a next-hop ip address of one of the pt-to-pt links instead it puts 0.0.0.0 in next-hop.
the route 192.101.254.252/32 is an IA ospf learned route and redistributed in bgp vrf VPN-NETWORKS.
when I do sh ip bgp , bgp is not able to work the next-hop. Does bgp think that they are equal cost multi-paths and gets confused ?
here is the out put for sh ip bgp
test-bsr-266#sh ip bgp
BGP table version is 14, local router ID is 192.101.254.243
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale, m multipath, b backup-path, f RT-Filter,
x best-external, a additional-path, c RIB-compressed,
Origin codes: i - IGP, e - EGP, ? - incomplete
RPKI validation codes: V valid, I invalid, N Not found
Network Next Hop Metric LocPrf Weight Path
*> 192.101.254.252/32 0.0.0.0 4 32768 ?
On IOS 15.2.1 SY bgp becomes intelligent and adds one of the equal cost links as the next-hop but on IOS 15.1.2 SY7 it does not.
any help would be appreciated.
