Abstract:
A system for PIM vLAG fast link failover recovery includes a first vLAG switch connected to a second vLAG switch by an ISL. The first vLAG switch is connected to an upstream network device by a failed link and the second vLAG switch is connected to the upstream network device by a functional link. To recover from the failed link, the first vLAG switch transmits a ROUTEUPDATE message to the second vLAG switch upon the ISL that instructs the second vLAG switch to receive data traffic from the upstream network device and forward the data traffic to the first vLAG switch upon the ISL.
