IP RIP SPLIT-HORIZON
Syntax
ip rip split-horizon
[poisoned]
Parameters
poisoned
Assigns a hop value of infinity (16) to routes in the routing updates
when the packets are transmitted from the same interfaces on
which the routes were learned.
Mode
VLAN Interface mode
Description
Use this command to activate split horizon or split horizon with poison
reverse on a routing interface to prevent routing loops caused by slow
convergence of RIP. By default, split horizon with poison reverse is
activated. You can configure only one interface at a time with this
command.
Routing updates that are transmitted from a routing interface on which split
horizon is activated do not contain any of the routes that were learned on
that interface, from its neighboring routing device.
Routing update packets that are transmitted from a routing interface on
which split horizon with poison reverse is activated contain the routes that
were learned on that interface, but the routes are given a hop count of
infinity (16) to indicate that they are unusable.
