Most routing protocols have metric structures and
algorithms that are not compatible with other protocols. In
a network with multiple routing protocols, the exchange of
route information and the capability to select the best
path across the multiple protocols are critical.
Administrative distance is the feature that routers use in
order to select the best path when there are two or more
different routes to the same destination from two different
routing protocols. Administrative distance defines the
reliability of a routing protocol. Each routing protocol is
prioritized in order of most to least reliable (believable)
with the help of an administrative distance value.
Ex:
1.AD value of Connected interface is - 0
2.Static route is- 1
3.RIP is 120
4.OSPF is 110
5.IGRP is 100
6.EIGRP is 90
7.BGP is 200
etc..
