Have you looked at using two interfaces to loop traffic with one interface in the global table and one in the VRF? You could run two different OSPF processes to transport routes between assuming you only need a default inside the VRF. I haven't needed to get this to work with iBGP, but if that is a requirement you will need an IOS capable of per-VRF Router ID to peer on the same router. (http://www.cisco.com/en/US/docs/ios/12_2sr/12_2sra/feature/guide/srbgprid.html) Off the cuff configuration example. These two interfaces would need to be crossed-over, but I'm assuming you have plenty of port density on a 6500. interface GigabitEthernet2/15 description Loop entering VRF mac-address 020x.xxxx.xx0e ip address 172.23.254.1 255.255.255.252 interface GigabitEthernet2/16 description Loop leaving VRF mac-address 020x.xxxx.xx0f ip vrf forwarding VRFname ip address 172.23.254.2 255.255.255.252 router ospf 215 network 172.23.254.1 0.0.0.0 area 0 default-information originate router ospf 216 vrf VRFname network 172.23.254.1 0.0.0.0 area 0 _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
