Abstract:
1. A method for forwarding multicast traffic, the method comprising: receiving, by a first node, a first multicast join message; in response to receiving the first multicast join message, establishing, by the first node, a primary path from the first node to a second node; receiving, by the first node, a second multicast join message carrying path information of the primary path; in response to receiving the second multicast join message, establishing a secondary path from the first node to the second node; sending, by the first node, a first multicast packet through the primary path without sending the first multicast packet through the secondary path; receiving, by the first node, fault information comprising the path information of the primary path; and sending a second multicast packet through the secondary path in response to the received path information of the primary path.
