Abstract
A system for PIM fast failover recovery includes a network of a plurality of switching devices. The plurality of switching devices includes a source switching device near a source communicatively connected to a receiver switching device near a receiver by a first interface and at least a third switching device that is communicatively connected to the receiver switching device by a second interface and further is communicatively connected to the source switching device by a third interface. The receiver switching device may discover that the first interface has failed and responds by sending the third switching device a PIM graft message prior to deleting an associated first interface route entry.
