Important Considerations

Your system always implements Split Horizon , a scheme that aims to

avoid the problems that are associated with reverse-route updates

(that is, the updates that are sent to a neighboring router that include

the routes that are learned from that router). The scheme omits the

routes that are learned from one neighbor in the updates that are sent

to that neighbor (the reverse routes). Poison reverse works with Split

Horizon as follows:

When you enable Poison Reverse for use with the Split Horizon

scheme (the default), the system advertises reverse routes in

updates, but sets the metrics to 16 (infinity). Setting the metric to

infinity breaks the loop immediately when two routers have routes

that point to each other.

When you disable Poison Reverse for the Split Horizon scheme,

reverse routes are simply not advertised.
