Re: mpls pe-ce

I wouldn't agree that Cisco would recommend RIP as best practice for a PE-CE
routing protocol. Every IGP - RIP, OSPF, EIGRP and ISIS (12.0S is limited)
is VRF aware and is supported as a PE-CE routing protocol in IOS. I don't
know where the original quote was pulled from, but each IGP above can be
used. It's also the reason there are extensions made to BGP to carry the
attributes (via extended communities) from these IGP's across an MPLS cloud
(metrics, route-types, etc.) The decision on which IGP to use will always
vary according to design requirements - like anything else.....
