Re: Routing protocol for MPLS

With my limited understanding, here are my answers:

1) No, it replaces ATM and FR.
2) Any interior routing protocol can be used. IS-IS, EIGRP, OSPF, RIP, etc.
3) I'd say it's layer 2.
4) Yes. I think you are referring to the popular product MPLS VPN. In
which case, MPLS traffic can be designated as belonging to a specific
customer.
