Configure VRF on 6500 using OSPF only

[cjkaufman@dmgov.org]

Is it possible to create a VRF using only OSPF as the routing protocol on a private network?  I've only been successful using BGP and redistributing OSPF.  I've inherited a network that had BGP configured for Public routes, but has since been dismantled, yet BGP is still being used to redistribute OSPF routes on our private network.  I would like to move away from BGP and use OSPF only.  Thus the reason for my initial question.

Hey Chris,

I am not able to fully understand your question however I might know what you are looking for, so have a look on this link:http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_ospf/configuration/15-sy/iro-15-sy-book/iro-sup-vrf.html#GUID-BDA07C45-20B3-4C59-A236-C2782A49700E

Otherwise, please let us know more.

HTH.

That could be what I am looking for.  Let me test and get back to you.  I just wanted to confirm that BGP was not required for VRF configuration/operation on Cisco 6500s.

FYI - I was able to get this working with the solution described in the this article:

I have read the article you linked above and performed some testing.  I have done some further research, and must clarify that the VRF I configured is not utilizing an ISP link.  This VRF is all internal on CE routers, no PE routers, so all my connections for the VRF are internal CE-CE. 

I still cannot get the VRF to populate the routing table with the OSPF routes on interfaces I have configured for the VRF.  If i configure BGP to redistribute the routes, then the routing table populates fine.  However I do not want to use BGP.

Please advise.

Hey,

I need some more information on it:

1. Are you saying that OSPF routes from VRF are not populating the global routing table after redistribution or,

2. You are unable to see the routes with in VRF?

I am unable to see the ospf routes in the VRF routing table. Thx

Provide the 'show run' from the router.

After additional research, it looks like I need to configure VRF-lite.  Please advise.
