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