642-780 MSPVM Maintaining Cisco Service Provider VPNs and MPLS Networks (MSPVM)

642-785 MSPQS Maintaining Cisco Service Provider Quality of Service (MSPQS)

       RIP

       OSPF

       BGP

       IS-IS

       IGRP

       EIGRP

Each routing protocol has its own Administrative Distance (AD), which is a value representing the trustworthiness of the specific routing protocol. If a router learns a destination route from two or more routing protocols, it selects the route from the protocol having the smallest Administrative Distance.

The below table shows the default Administrative Distance (AD) values for each routing protocol:

Now, if the router learns a specific destination route from both OSPF and RIP, it will select the route learned from OSPF because this protocol has a smaller AD compared to RIP (110 instead of 120).
