suresh In the EIGRP routing protocol, the concept of EIGRP successor and feasible successor plays a crucial role in determining the best and alternate paths for routing. When a router has calculated multiple paths to reach a destination, the successor route is the path with the lowest metric, which is considered the best path for forwarding packets.
On the other hand, a feasible successor is a backup path that has a metric lower than the current successor route but higher than the best path. This allows for fast convergence and redundancy in case the primary path fails.
By maintaining both successor and feasible successor routes, EIGRP can ensure efficient routing and reliable network connectivity by quickly switching to the backup path when necessary, thus optimizing network performance.
