Configuring IP Unicast Routing
Configuring Protocol-Independent Features
DETAILED STEPS
To remove a distance definition, use the no distance router configuration command.
EXAMPLE
In the following example, the routereigrp global configuration command sets up EIGRP routing in autonomous system
number 109. The network router configuration commands specify EIGRP routing on networks 192.168.7.0 and
172.16.0.0. The first distance command sets the administrative distance to 90 for all routers on the Class C network
192.168.7.0. The second distance command sets the administrative distance to 120 for the router with the address
172.16.1.3.
Switch# configure terminal
Switch(config)# router eigrp 109
Switch(config-router)# network 192.168.7.0
Switch(config-router)# network 172.16.0.0
Switch(config-router)# distance 90 192.168.7.0 0.0.0.255
Switch(config-router)# distance 120 172.16.1.3 0.0.0.255
Switch(config-router)# end
In the following example, the set distance is from the least to the most specific network:
Switch# configure terminal
Switch(config)# router eigrp 109
Switch(config-router)# distance 22 10.0.0.0 0.0.0.255
Switch(config-router)# distance 33 10.11.0.0 0.0.0.255
Switch(config-router)# distance 44 10.11.12.0 0.0.0.255
Switch(config-router)# end
Managing Authentication Keys
Key management is a method of controlling authentication keys used by routing protocols. Not all protocols can use key
management. Authentication keys are available for EIGRP and RIP Version 2.
Command Purpose
1. configure terminal Enter global configuration mode.
2. router { bgp | rip | ospf | eigrp } Enter router configuration mode.
3. distance weight { ip-address { ip-address mask }}
[ ip access list ]
Define an administrative distance.

weight —The administrative distance as an
integer from 10 to 255. Used alone, weight
specifies a default administrative distance
that is used when no other specification
exists for a routing information source.
Routes with a distance of 255 are not
installed in the routing table.

(Optional) ip access list —An IP standard or
extended access list to be applied to
incoming routing updates.
4. end Return to privileged EXEC mode.
5. show ip protocols Display the default administrative distance for a
specified routing process.
6. copy running-config startup-config (Optional) Save your entries in the configuration
file.
