Abstract
A method including receiving a multicast packet to route to a next multicast hop; determining that the next multicast hop is not available; performing unicast encapsulation to the multicast packet to generate a unicast-encapsulated multicast packet; and sending the unicast-encapsulated multicast packet, as a unicast transmission, via an alternate path relative to a multicast path, to the next multicast hop, wherein the alternate path is a unicast path to the next multicast hop.
