Abstract
Official abstract text for this publication.
An apparatus comprising a processor configured to send a first notification message to a first label switch router (LSR) to discover the upstream multipoint Label Distribution Protocol (mLDP) LSR, wherein the apparatus is configured to couple to the first LSR, and wherein the first LSR is not an mLDP LSR, receive a second notification message from the upstream mLDP node, and in response to receiving the second notification message, establish an mLDP Label Switch Path (LSP) to the upstream mLDP node via the first LSR.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: a transceiver; and a processor coupled to the transceiver and configured to: establish communications with a non-multipoint Label Distribution Protocol (non-mLDP) label switch router (LSR) via the transceiver, wherein the non-mLDP LSR does not support multipoint Label Distribution Protocol (mLDP), and wherein the non-mLDP LSR is positioned between an mLDP LSR and the apparatus; send a first notification message to the non-mLDP L…
