<p>The embodiment of the present invention discloses a method for establishing a multicast LSP and a system for transmitting multicast data. The method includes: an MSA node learns and stores multicast stream information; the egress edge node in the MPLS domain obtains the multicast stream information sent by the MSA node by sending a query request message to the MSA node; the egress edge node joins the multicast group according to the obtained multicast stream information, and establishes a multicast LSP between the ingress edge node and the egress edge node. The technical solution of the present invention supports dynamic implementation of multicast services, and reduces the cost of maintaining a network topology.</p> |
