Abstract
In one embodiment, a node in a multicast label distribution protocol (mLDP) network determines a remote protecting node for a particular root node in the mLDP network. In addition, the node determines a protecting node address of the remote protecting node and a root node address of the particular root node, and establishes an mLDP label-switched path (LSP) via the remote protecting node by using the protecting node address as a root of an outer forwarding equivalent class (FEC) of a recursive FEC, and using the root node address as an inner FEC of the recursive FEC for the mLDP LSP. As such, when the remote protecting node is reached, the outer FEC is stripped and the remote protecting node continues establishing the mLDP LSP toward the particular root node.
