Abstract:
In one aspect, the disclosure includes an apparatus comprising a processor configured to function as a merge point (MP) in a point to multi-point (P2MP) backup label switching path (LSP) for a primary LSP, receive P2MP backup LSP information originating from a protected node, wherein the P2MP backup LSP information comprises the identity of a point of local repair (PLR), determine a backup label switching router (LSR), and send a message with the identity of the backup LSR to an upstream node.
