Abstract
A network device receives multi-destination packets from a first node and forwards at least a first of the multi-destination packets to another network device using a first multi-destination tree with respect to the network device. The network device detects that a link associated with the first multi-destination tree satisfies one or more criteria and, in response to detecting that the link satisfies the one or more criteria, selects a second multi-destination tree with respect to the network device. The network device forwards at least a second of the multi-destination packets to the other network device using the second multi-destination tree.
