Abstract
An RB device creates a primary multicast tree and a corresponding backup multicast tree, and determines whether the primary multicast tree for forwarding traffic fails or not, according to a received first LSP packet; when the primary multicast tree fails, the RB device forwards the traffic using the backup multicast tree.
Claims12
A method for forwarding traffic, the method comprising:
- creating, by an RB device, a primary multicast tree and a corresponding backup multicast tree;
- determining, by the RB device, whether the primary multicast tree for forwarding traffic fails or not, according to a received first Link State Protocol data (LSP) packet;
- and
- forwarding, by the RB device, the traffic using the backup multicast tree when the primary multicast tree fails.

An RB device, comprising a processor and a non-transitory machine readable storage medium storing machine readable instructions which are executable by the processor to:
- create a primary multicast tree and a corresponding backup multicast tree;
- determine whether the primary multicast tree for forwarding traffic fails or not, according to a received first Link State Protocol data (LSP) packet;
- and
- forward the traffic using the backup multicast tree when the primary multicast tree fails.
