Abstract
Multicast error detection and recovery may be provided. A join request for a multicast stream may be sent from a first network node to a second network node. The join request may be sent over a first link of a plurality of links between the first network node and the second network node. A redirect message indicating that the second network node cannot accommodate the join request may be received by the first network node from the second network node. In response to receiving the redirect message, the join request for the multicast stream may not be sent on a second link of the plurality of links by the first network node to the second network node. And in response to receiving the redirect message, an alternate upstream network node may be determined by the first network node to send the join request for the multicast stream to.
