The output from the show ip route privileged EXEC command lists codes for the routing protocols. The
Figure 10-1 shows the default administrative distances for these routing protocols.
Monitoring Static Routes
You can display statistics about static routes with the show ip route command. For more show ip
privileged EXEC command options and for explanations of fields in the resulting display, refer to the
Cisco IOS IP and IP Routing Command Reference publication.
This is an example of the privileged EXEC command show ip route with a static route configured:
Router# show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
