Configuring RIP Examples

The following example enables RIP on both FastEthernet interfaces and a serial link of the XSR. The FastEthernet 2 interface is configured to be totally passive (updates not sent or received).

The serial interface uses split horizon with poison reverse while the others use split horizon (the default). Authentication mode text is used on Serial 1/0, and the key string is Mexico:

XSR(config)#interface fastethernet 1

XSR(config-if<F1>)#ip address 192.168.1.1 255.255.255.0

XSR(config-if<F1>)#no shutdown

XSR(config)#interface fastethernet 2

XSR(config-if<F2>)#no shutdown

XSR(config-if<F2>)#ip address 192.169.1.1 255.255.255.0

XSR(config)#interface serial 1/0

XSR(config-if<S1/0>)#ip address 192.5.10.2 255.255.255.0

XSR(config-if<S1/0>)#ip split-horizon poison

XSR(config-if<S1/0>)#ip rip authentication key-string Mexico

XSR(config-if<S1/0>)#ip rip authentication mode text

XSR(config-if<S1/0>)#encapsulation ppp

XSR(config-if<S1/0>)#no shutdown

XSR(config)#router rip

XSR(config-router)#network 192.168.1.0

XSR(config-router)#network 192.169.1.0

XSR(config-router)#network 192.5.10.0

XSR(config-router)#passive-interface fastethernet 2

XSR(config-router)#no receive-interface fastethernet 2

The following RIP example sets an Access Control List (ACL) to allow packets from the address of 192.168.1.xxx and 154.68.1.xxx (where xxx are any valid numbers) only through the XSR's F1 port.

XSR(config)#interface FastEthernet 1

XSR(config-if<F1>#no shutdown
