Ip Rip Poison-Reverse Command; Ip Rip Split-Horizon Command - Avaya P333R-LB User Manual

ip rip poison-reverse Command

Use the ip rip poison-reverse command 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-horizon command 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
