276 Chapter 5 � IP Routing
The Show IP Protocol Command
The show ip protocol command shows you the routing protocols that are
configured on your router. Notice in the following output that both RIP and
IGRP are running on the router, but only IGRP appears in the routing table
because of its lower administrative distance.
The show ip protocols command also displays the timers used in the
routing protocol. Notice in the output below that RIP is sending updates
every 30 seconds, which is the default. Notice further down that RIP is routing
for network 172.16.0.0, and the two neighbors it found are 172.16.40.2
and 172.16.20.1.
