Abstract
Techniques are described for signaling a resource reservation point-to-multipoint (P2MP) label switched path (LSP) in a ring network. For example, the techniques include sending a single resource reservation request message without the ingress needing to send multiple resource reservation request messages, one for each leaf network device of the P2MP ring LSP. The resource reservation request message includes a leaf identification object from which network devices of a P2MP ring LSP may explicitly or implicitly identify themselves as prospective leaf network devices of the P2MP ring LSP. A network device determined to be a leaf network device may send a resource reservation response message back to the ingress network device of the P2MP ring LSP and send a modified resource reservation request message (if explicit) and/or the same resource reservation request message (if implicit) to a next hop network device along the P2MP ring LSP.
