Abstract
Techniques for providing resilient multicast traffic processing in a network element are described herein. In one embodiment of the invention, a network element separately joins equivalent multicast traffic streams at a first and second interface respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives at the first interface and drops the packets of the equivalent multicast traffic stream it receives at the second interface. Upon an interruption of the packets of the multicast traffic stream being received at the first interface, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives at the second interface. Other methods and apparatuses are also described.
