Finish the following tasks before configuring the RIP network optimization.
Configure network addresses on interfaces, and make sure neighboring nodes
■
are reachable
Configure basic RIP functions.
■
Follow these steps to configure RIP timers:

To do...

Enter system view
Enter RIP view
Configure values for RIP
timers
Based on the network performance, you should make RIP timers of RIP routers
identical to each other to avoid unnecessary traffic or route oscillation.
If both the split horizon and poison reverse are configured, only the poison reverse
function takes effect.
Configure split horizon
The split horizon function disables an interface from sending routes received by
the interface itself, so as to prevent routing loops between adjacent routers.
Follow these steps to configure the split horizon function:
To do...
Enter system view

Enter interface view

Enable split horizon
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
Use the command...
system-view
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
timers { garbage-collect
garbage-collect-value | suppress
suppress-value | timeout
timeout-value | update
update-value }*
Use the command...

interface-number
rip split-horizon
