1. A method for multicast fast failover handling in a network comprising:
calculating failover meta data for each failover route of a plurality of failover routes for a network;
grouping each failover route of the plurality of failover routes into a split failover route grouping based on the failover meta data;
for all split failover route groupings, calculating one or more path segments, wherein a path segment comprises one or more connections between networking devices on the network, the one or more connections are common to the failover routes of a given split failover route grouping, and the path segment ends at a networking device where two or more failover routes of the plurality of failover routes diverge from each other;
performing collision detection between the split failover trace groupings to identify path segments that collide; and
applying route tagging operations to network failover traffic for the path segments that collide.
