| 主权项 | 1. A method of Path Computation Element (PCE) Communication Protocol (PCEP) communication, comprising: sending, to a PCE, a request to compute a backup ingress node for a Point-to-Multipoint (P2MP) Label Switched Path (LSP) in a network; and receiving, from the PCE, the backup ingress node for the P2MP LSP in accordance with the request, wherein the request includes a plurality of flags including a backup ingress bit (I) flag for the P2MP LSP. | ||
