MPLS Point-to-Multipoint Traffic Engineering
The MPLS Point-to-Multipoint (P2MP) feature enables forwarding of information from a single
source to multiple destinations along an optimized MPLS path. P2MP feature is ideal for
transporting multicast data traffic, leveraging MPLS, and using optimal bandwidth utilization of the
network’s links.
The P2MP feature supports the following RFCs:
• RFC 4875: Extensions to Resource Reservation Protocol - Traffic Engineering (RSVP-TE) for
Point-to-Multipoint TE Label Switched Paths (LSPs)
• RFC 4461: Signaling Requirements for Point- to-Multipoint Traffic-Engineered MPLS Label
Switched Paths (LSPs)
• RFC 2961: RSVP Refresh Overhead Reduction Extensions
• RFC 3209: RSVP-TE: Extensions to RSVP for LSP Tunnels
• RFC 2205: Resource ReSerVation Protocol (RSVP) -- Version 1 Functional Specification
Figure 10 shows the network topology of a P2MP network.
