Abstract

Techniques include providing ingress protection for multipoint label switched paths (LSPs). According to the techniques, a primary ingress node and a backup ingress node of a network are both configured to advertise a virtual node identifier of a virtual node as a next hop for a multicast source. Two or more egress nodes of the network then use the virtual node as a root node reachable through the primary ingress node to establish a multipoint LSP. After the multipoint LSP is established, the primary ingress node forwards traffic of the multicast source on the multipoint LSP. When failure occurs at the primary ingress node, the backup ingress node forwards the traffic of the multicast source along a backup path and onto the same multipoint LSP with the virtual node as the root node reachable through the backup ingress node. The techniques enable ingress protection without tearing down the multipoint LSP.
