What happens when a router has two routing protocols running and is receiving similar routes from each routing protocol?
Easy question, right? The routing protocol with the lower administrative distance has its routes installed in the routing table (routing information base – RIB).
However, an interesting question that comes up from time to time is this:
What if I configure the administrative distance to be the same for two routing protocols? Will the router install routes from each routing protocol and allow me to load balance traffic?
