Interface Configuration.
Enables split-horizon with poison reverse on an interface. The no form of
this command disables the poison-reverse mechanism. The default state is
split-horizon with poison reverse.
The split-horizon technique prevents information about routes from exiting
the router interface through which the information was learned. 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.
To Enable:
ip rip poison-reverse
To Disable:
no ip rip poison-reverse
The following example enables split-horizon with poison reverse on
interface labeled "boston".
(config-if:boston)# ip rip poison-reverse
P550R, P580, P880, and P882.
