System and method for computing a backup egress of a point-to-multi-point label switched path
An apparatus for requesting computation of a backup egress path comprising a processor configured to send a path computation element (PCE) protocol (PCEP) request (PCReq) message requesting computation of the backup egress path to protect against a fault in a primary egress path of a Point to Multi-Point (P2MP) or Point-to-Point (P2P) label switched path (LSP), wherein the backup egress path extends from a previous-hop internal node of the primary egress node of the P2MP or P2P LSP to a backup egress node. A method for advertising or discovering a backup egress path computation capability comprising exchanging a message that indicates that a PCE comprises a backup egress path computation capability.
