ip rip poison-reverse Command

Use the ip rip poison-reversecommand to enable split-horizon with poison-reverse on an interface. The no form of this command disables the poison- reverse mechanism.

The split-horizon technique prevents information about routes from exiting the router interface through which the information was received. This prevents routing loops.

Poison reverse updates explicitly indicate that a network or subnet is unreachable rather than implying they are not reachable. Poison reverse updates are sent to defeat large routing loops.

The syntax for this command is:

[no] ip rip poison-reverse

ip rip split-horizon Command

Use the ip rip split-horizoncommand to enable split-horizon mechanism. The no form of this command disables the split-horizon. By default split-horizon is enabled.

The split-horizon technique prevents information about routes from exiting the router interface through which the information was received. This prevents routing loops.

The syntax for this command is:

[no] ip rip split-horizon

Example:

Router-N(config-if:marketing)# no ip rip split-horizon
