Ccna Certification Training: Configuring Static Routes On A Cisco Router

First, resist the temptation to say “I would fix it, but I’m too busy talking to you”.

Second, use a quick fix to get the issue resolved temporarily while you resolve the issue.

Static routes are a great quick fix. You can use a static route to get the users where they need to be, which gives you time to find out what the problem is with the dynamic routing protocol. (You must also resist the temptation to apply a static route and declare the problem fixed!)

Static routes are configured with the ip route command, followed by the destination network and mask. After that, you must specify either the next-hop IP address or the local exit interface. Both of the following masks are acceptable:

ip route 172.10.1.0 255.255.255.0 210.1.1.1

ip route 172.10.1.0 255.255.255.0 serial0

Using IOS Help on a Cisco router shows the various options:

R1(config)#ip route ?

A.B.C.D Destination prefix

profile Enable IP routing table profile

vrf Configure static route for a VPN Routing/Forwarding instance

R1(config)#ip route 172.10.1.0 ?

A.B.C.D Destination prefix mask

R1(config)#ip route 172.10.1.0 255.255.255.0 ?

A.B.C.D Forwarding router's address

BRI ISDN Basic Rate Interface

Dialer Dialer interface

Loopback Loopback interface

Null Null interface

Serial Serial

TokenRing IEEE 802.5

Remember, you're specifying either the next-hop router's IP address or the local router's exit interface!

Configuring static routes is a great skill to have in the network room and in the CCNA exam room. Be ready to configure them in either situation!
