FAST CONVERGENCE WITH MULTICAST SOURCE MOBILITY

摘要

In one embodiment, a method includes discovering at a first edge device in a first network that a multicast source has moved from the first network to a second network, the first edge device in communication through a core network with a plurality of edge devices belonging to a multicast group comprising the multicast source, transmitting from the first edge device to a second edge device in the second network, a join request for the multicast group comprising the multicast source at the second network, receiving multicast traffic for the multicast group at the first edge device on a transient multicast tree extending from the second edge device to the plurality of edge devices, and forwarding the multicast traffic to the plurality of edge devices. An apparatus and logic are also disclosed herein.

1. A method comprising:
discovering at a first edge device in a first network that a multicast source has moved from said first network to a second network, said first edge device in communication through a core network with a plurality of edge devices belonging to a multicast group comprising the multicast source; transmitting from said first edge device to a second edge device in said second network, a join request for the multicast group comprising the multicast source at said second network; receiving multicast traffic for the multicast group at said first edge device on a transient multicast tree extending from said second edge device to said plurality of edge devices; and forwarding the multicast traffic to said plurality of edge devices.
