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.
rip [ process-id ] [ vpn-instance

3. Specify the interval for
sending RIP packets and the

packets that can be sent at
each interval.

Optional.
By default, an interface sends up to
three RIP packets every 20
milliseconds.
Configuring RIP FRR
When a link in a RIP network fails, the traffic is interrupted until RIP completes routing convergence based
on the new network topology.
You can enable RIP fast reroute (FRR) to reduce traffic recovery time.
Figure 6 Network diagram for RIP FRR
In Figure 6, after you enable FRR on Router B, RIP designates a backup next hop using a routing policy
when a network failure is detected. Packets are then directed to the backup next hop to reduce traffic
recovery time. At the same time, RIP calculates the shortest path based on the new network topology, and
forwards packets over that path after network convergence.
Configuration prerequisites
Specify a next hop by using the apply fast-reroute backup-interface command in a routing policy and
reference the routing policy with RIP FRR. For more information about routing policy configuration, see
"Configuring routing policies."
Configuration guidelines
• RIP FRR is only effective for non-recursive RIP routes (that are learned from directly connected
neighbors).
• Do not use RIP FRR and BFD (for RIP) at the same time. Otherwise, RIP FRR might fail to take effect.
