Point-to-Multipoint LSPs Overview
A point-to-multipoint MPLS LSP is an RSVP-TE LSP with a single ingress LSR and one
or more egress LSRs. You can use point-to-multipoint LSPs to avoid unnecessary
duplication of packets at the ingress router by allowing non-ingress LSRs to replicate
the incoming data on one or more outgoing interfaces. Point-to-multipoint LSPs for
multicast VPNs are supported for intra-autonomous system (AS) environments (within
an AS), but are not supported for inter-AS environments (between ASs).
