Configuring a preference for RIPng
Routing protocols each have a preference. When they find routes to the same destination, the route found
by the routing protocol with the highest preference is selected as the optimal route. You can manually set
a preference for RIPng. The smaller the value, the higher the preference.
To configure a preference for RIPng:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIPng view.
ripng [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Configure a preference for
RIPng. preference [ route-policy
route-policy-name ] value
The default setting is 100.

Configuring RIPng route redistribution
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIPng view.
ripng [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Redistribute routes from other
routing protocols.
import-route protocol [ process-id ]
[ allow-ibgp ] [ cost cost |
route-policy route-policy-name ] *
By default, RIPng does not
redistribute routes from other
routing protocols.
4. (Optional.) Configure a
default routing metric for
redistributed routes.
default cost cost
The default metric of redistributed
routes is 0.

Tuning and optimizing the RIPng network
This section describes how to tune and optimize the performance of the RIPng network as well as
applications under special network environments.
Before you tune and optimize the RIPng network, complete the following tasks:
• Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring nodes.
• Configure basic RIPng.

Configuring RIPng timers
You can adjust RIPng timers to optimize the performance of the RIPng network.
When you adjust RIPng timers, consider the network performance, and perform unified configurations on
routers running RIPng to avoid unnecessary network traffic or route oscillation.
To configure RIPng timers:
