DYNAMIC DETERMINATION OF THE ROOT NODE OF AN MLDP TUNNEL

摘要

A capability is provided for dynamically determining the root node of a Multicast Label Distribution Protocol (MLDP) tunnel. A request to join a multicast group is received, where the multicast group is supported by a multicast source. A route to the multicast source is determined. A next-hop node associated with the route and a routing protocol used to advertise the route to the next-hop node are determined based on the route. An advertising node that used the routing protocol to advertise the route to the next-hop node is determined based on the routing protocol and the next-hop node. The advertising router is the root of the MLDP tunnel.
