[RFC4364] and [RFC4659] define a Layer 3 VPN service known as BGP/ MPLS VPNs for IPv4 and for IPv6, respectively. [RFC2205] defines the Resource Reservation Protocol (RSVP), which may be used to perform admission control as part of the Integrated Services (Int-Serv) architecture [RFC1633][RFC2210].

   Support for the Resource Reservation Protocol (RSVP) in Layer 3 VPNs


   RFC 4364 and RFC 4659 define an approach to building provider-    provisioned Layer 3 VPNs (L3VPNs) for IPv4 and IPv6.  It may be    desirable to use Resource Reservation Protocol (RSVP) to perform    admission control on the links between Customer Edge (CE) routers and    Provider Edge (PE) routers.  This document specifies procedures by    which RSVP messages traveling from CE to CE across an L3VPN may be    appropriately handled by PE routers so that admission control can be    performed on PE-CE links.  Optionally, admission control across the    provider's backbone may also be supported.
