Always believed MPLS only runs on IS-IS and OSPF as backbone IGP. Is it possible to use EIGRP as a backbone IGP as well?
My customer uses EIGRP right now and we want to migrate VRF-lite to a real MPLS cloud. Can I re-use EIGRP?
For plain MPLS, there is no restriction that you need OSPF or ISIS. But when you plan to implement MPLS TE, you need a link state protocol. So if you dont have any plan to go for Traffic Engg, I think you can continue with EIGRP.
