Setting the interval for sending triggered updates
Perform this task to avoid network overhead and reduce system resource consumption caused by
frequent RIPng triggered updates.
You can use the timer triggered command to set the maximum interval, minimum interval, and
incremental interval for sending RIPng triggered updates.
For a stable network, the minimum interval is used. If network changes become frequent, the
triggered update sending interval is incremented by the incremental interval × 2
n-2
for each triggered
update until the maximum interval is reached. The value n is the number of triggered update times.
To set the interval for sending triggered updates:
Step

Remarks
1. Enter system view.

2. Enter RIPng view.

By default:
• The maximum interval is 5
seconds.
• The minimum interval is 50
milliseconds.
• The incremental interval is 200
milliseconds.
Configuring RIPng GR
GR ensures forwarding continuity when a routing protocol restarts or an active/standby switchover
occurs.
Two routers are required to complete a GR process. The following are router roles in a GR process:
• GR restarter—Graceful restarting router. It must have GR capability.
• GR helper—A neighbor of the GR restarter. It helps the GR restarter to complete the GR
process.
After RIPng restarts on a router, the router must learn RIPng routes again and updates its FIB table,
which causes network disconnections and route reconvergence.
With the GR feature, the restarting router (known as the GR restarter) can notify the event to its GR
capable neighbors. GR capable neighbors (known as GR helpers) maintain their adjacencies with
the router within a configurable GR interval. During this process, the FIB table of the router does not
change. After the restart, the router contacts its neighbors to retrieve its FIB.
By default, a RIPng-enabled device acts as the GR helper. Perform this task on the GR restarter.
IMPORTANT:
You cannot enable RIPng NSR on a device that acts as GR restarter.
To configure GR on the GR restarter:
