System and method for protecting ingress and egress of a point-to-multipoint label switched path
A network comprising a first edge node, a second edge node, a third edge node that backs up either the first edge node or the second edge node, and an internal node coupled to the first edge node, the second edge node, and the third edge node, wherein a point-to-multipoint (P2MP) label switched path (LSP) extends across the network from the first edge node, through the internal node, and to the second edge node, and wherein a LSP sub-tree extends between the third edge node and the internal node, but does not extend across the network.
