Chapter 5 Configuring the Router

Performing the Initial Configuration on the Router

Examples

Specifying a Default Route: Example

!

ip routing

!

ip route 192.168.24.0 255.255.255.0 172.28.99.2

!

ip default-network 192.168.24.0

Sample Output for the show ip route Command

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

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, * - candidate default

Gateway of last resort is 172.28.99.2 to network 192.168.24.0

172.24.0.0 255.255.255.0 is subnetted, 1 subnets

C 172.24.192.0 is directly connected, FastEthernet0

S 172.24.0.0 255.255.0.0 [1/0] via 172.28.99.0

S* 192.168.24.0 [1/0] via 172.28.99.2

172.16.0.0 255.255.255.0 is subnetted, 1 subnets

C 172.16.99.0 is directly connected, FastEthernet1

Router#

Step 4 ip route dest-prefix mask next-hop-ip-address

[admin-distance] [permanent]

Example:

Router(config)# ip route 192.168.24.0

255.255.255.0 172.28.99.2

Establishes a static route.

Step 5 ip default-network network-number

or

ip route dest-prefix mask next-hop-ip-address

Example:

Router(config)# ip default-network 192.168.24.0

Example:

Router(config)# ip route 0.0.0.0 0.0.0.0

172.28.99.1

Selects a network as a candidate route for computing the gateway of last resort.Creates a static route to network 0.0.0.0 0.0.0.0 for computing the gateway of last resort.

Step 6 end

Example:

Router(config)# end

Returns to privileged EXEC mode.

Step 7 show ip route

Example:

Router# show ip route

Displays the current routing table information.

• Verify that the gateway of last resort is set.
