I have a few 7.2.1 routers with iBGP and multiple VRFs, trying to figure out how to leak routes between VRFs.

Static routes work ok (route + 2x routing rules with lookup in another table) but the wiki says:
"In general it is recommended that all routes between VRF should be exchanged using BGP local import and export functionality."

How exactly would this be achieved? I can figure out a few overly complicated hacks to do it (including a cable from one port to another) but not the clean way.

At the moment there is no easy mechanism to do this. What may work is setting two BGP instances, one per VRF, and making a BGP session internally between vrfs.

Thanks for the lightning fast response!
So would this be best practice then?

• Create loopback bridge in both VRFs
• Leak routes (static route + rules) to loopbacks between VRFs
• Setup BGP between loopbacks

It's not like best practice, but rather a workaround that might work.

Ok, just for reference how does this work on v6 then?
