Command Reference RIPng Commands
Use the split-horizon command to enable the RIPng split-horizon function in routing process
configuration mode. Use the no form of this command to disable this function. Use the split-horizon
poisoned-reverse command to enable the RIPng poisoned reverse horizontal split function in routing
process configuration mode. Use the no form of this command to disable this function.
split-horizon [ poisoned-reverse ]
no split-horizon [ poisoned-reverse ]
(Optional) Enables the poisoned-reverse horizontal split.
RIPng split horizon is enabled by default.
Routing process configuration mode.
In the process of packet updating, split-horizon function prevents some routing information from being
advertised through the interface learning those routing information. The poisoned reverse horizontal
split function advertises some routing information to the interface learning those routing information,
and the metric value is set as 16. The RIPng routing protocol belongs to the distance vector routing
protocol, so the horizontal split shall be noticed in the actual application. You can use the show ipv6
rip command to determine whether the RIPng split-horizon function is enabled or not.
The following example shows how to disable the RIPng horizontal split:
Ruijie(config)# ipv6 router rip
Ruijie(config-router)# no split-horizon
