Configuring the RIP packet sending rate
Perform this task to specify the interval for sending RIP packets and the maximum number of RIP packets
that can be sent at each interval. This feature can avoid excessive RIP packets from affecting system
performance and consuming too much bandwidth.
To configure the RIP packet sending rate:

Command… Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.

3. Specify the interval for
sending RIP packets and the
maximum number of RIP
packets that can be sent at
each interval.

By default, an interface sends up to
three RIP packets every 20
milliseconds.
Configuring RIP 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 RIP restarts on a router, the router must learn RIP routes again and update 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") keep their adjacencies with the
router within a 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 RIP-enabled device acts as the GR Helper. Perform this task on the GR Restarter.
To configure GR on the GR Restarter:
