ip rip poisoned-reverse 231
ip rip poisoned-reverse
Configures the interface to implement poison reverse. Poison Reverse is a stronger form of split
horizon. Routers do not omit destinations learned from an interface; instead, routers include
these destinations in updates, but advertise an infinite cost to reach them. This parameter
increases the size of routing updates. In addition, it provides a positive indication that a specific
location is not reachable through a router.
The no form of the command disables poisoned reverse.
