Configure RIPng timers
When adjusting RIPng timers, you should consider the network performance and
perform unified configurations on routers running RIPng to avoid unnecessary
network traffic increase or route oscillation.
If both the split horizon and poison reverse are configured, only the poison reverse
function takes effect.
Configure the split horizon
The split horizon function disables a route learned from an interface from being
advertised via the interface to prevent routing loops between neighbors.
Follow these steps to configure the split horizon:
To do...
Enter system view
Enter interface view

In Frame Relay, X.25 and other non-broadcast multi-access (NBMA) networks,

split horizon should be disabled if multiple VCs are configured on the primary
interface and secondary interfaces to ensure route advertisement. For detailed
