Abstract
A first message, received from a first device, identifies a multicast distribution tree and includes first information associated with a route leading to a root of the multicast distribution tree. A second message, received from a second device, also identifies that tree, but the second message includes second information, which conflicts with the first information. In one embodiment, the conflict is resolved by building a first version of the tree based on the first information and building a second version of the tree based on the second information. The first version is used to forward multicast packets to the first device, while the second version is used to forward multicast packets to the second device. In another embodiment, the conflict is resolved by selecting either the first information or the second information, based on a policy, and then building a single version of the tree corresponding to the selected information.
