Configuring Rip Frr - HP 3600 v2 series Configuration Manual

To do...
Enable a RIP process and enter RIP
view
Configure the maximum number of
RIP packets that can be sent at the
specified interval

Configuring RIP FRR

NOTE:
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 may fail to take effect.
•
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 9 Network diagram for RIP FRR
In Figure 9, 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 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 the path after network convergence.
Configuration prerequisites
You need to 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 the chapter "Routing policy configuration."
Configuration procedure
Follow these steps to configure RIP FRR:
To do...
Enter system view
Configure the source address of
echo packets
Use the command...
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
output-delay time count count
Use the command...
system-view
bfd echo-source-ip ip-address
35
Remarks
––
Optional
By default, an interface sends up to
three RIP packets every 20
milliseconds.
