Chapter 5 Basic Router Configuration
Configuring Dynamic Routes
Example
In the following configuration example, the static route sends out all IP packets with a destination IP address of 192.168.1.0 and a subnet mask of 255.255.255.0 on the Fast Ethernet interface to another device with an IP address of 10.10.10.2. Specifically, the packets are sent to the configured PVC.
You do not need to enter the command marked “(default).” This command appears automatically in the configuration file generated when you use the show
!
ip classless (default)
ip route 192.168.1.0 255.255.255.0 10.10.10.2!
Verifying Configuration
To verify that you have properly configured static routing, enter the show ip route command and look for static routes signified by the “S.”
You should see a verification output similar to the following:
Router# show ip route |

Configuring Dynamic Routes
In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. Changes in dynamic routes are shared with other routers in the network.
The Cisco routers can use IP routing protocols, such as Routing Information Protocol (RIP) or Enhanced Interior Gateway Routing Protocol (EIGRP), to learn routes dynamically. You can configure either of these routing protocols on your router.
