WebThe EIGRP algorithm (DUAL FSM) uses the feasibility condition to build the topology table. If a Feasible Successor exists (that is, the neighbor meets the Feasibility Condition), then it is placed in the topology table and the route is considered as Passive, which means that it can be used immediately if the primary route goes down.

WebDec 2, 2016 · The Feasible Successor Condition Met on Router R1. Just by virtue of the fact that the route via router R3 (that is, via 10.1.1.6) appears in the output of the show ip eigrp topology command issued on router R1, we can conclude that the path via R3 is indeed a feasible successor route. However, let’s examine the output a bit more closely … WebThe successor is a term that the EIGRP routing protocol uses. It is the best route to a certain destination, the route that will be installed in the routing table. The next best path (that passes certain criteria) is called the feasible successor.
