Summary of this draft Motivation Provide robust MPLS services to customers as NGN services Can offer end-to-end paths using LDP Can’t offer end-to-end MPLS TE LSPs between customer sites Want to provide CE-to-CE MPLS TE LSPs Guarantee bandwidth, Provide fast protection, diversely routed path …… Provide all of the benefits of a L3VPN Offer vrf instance per customer to avoid security issues Customers can not forward packets through the service provider’s general forwarding instance. They can not join the service provider’s routing domain and MPLS signaling domain. Assign address space that is unique only to a VPN The important thing is that Most carriers and service providers deploy L3VPN (not L1VPN) Don’t see L1VPN solution |
