This chapter condenses the CCNA Routing commands into an easy-to-use chart for quick reference.

This chapter provides information and commands concerning the following topics:

Static Routing

When using the ip route command, you can identify where packets should be routed to in two ways:

Both ways are shown in both the "Configuration Example: Static Routes" section and the "Default Routing" section.

Router(config)#ip route 172.16.20.0 255.255.255.0 172.16.10.2

172.16.20.0 = destination network

255.255.255.0 = subnet mask

172.16.10.2 = next-hop address

Read this to say: To get to the destination network of 172.16.20.0, with a subnet mask of 255.255.255.0, send all packets to 172.16.10.2

Router(config)#ip route 172.16.20.0 255.255.255.0 s0/0

172.16.20.0 = destination network

255.255.255.0 = subnet mask

s0/0 = exit interface

Read this to say: To get to the destination network of 172.16.20.0, with a subnet mask of 255.255.255.0, send all packets out interface Serial 0/0
