Abstract
An apparatus comprising a processor configured to store a first upstream label in a forwarding table upon receipt of a first message encapsulating the first upstream label from a first adjacent node, store a first downstream label in the forwarding table upon receipt of a second message encapsulating the first downstream label from a second adjacent node, send a third message encapsulating a second downstream label to the first adjacent node, send a fourth message encapsulating a second upstream label to the second adjacent node; and forward data received from a plurality of adjacent nodes over a MP2MP LSP using at least a portion of the labels stored in the forwarding table, wherein each adjacent node is associated with only one upstream label and only one downstream label, and wherein the maximum state complexity of the forwarding table is linear relative to the number of adjacent nodes.
