Tuning and optimizing RIP networks
Before you tune and optimize RIP networks, complete the following tasks:
•
Configure IP addresses for interfaces, and make sure that all neighboring nodes can reach each
other.
•
Configure RIP basic functions.
Configuring RIP timers
You can change the RIP network convergence speed by adjusting RIP timers. Based on network
performance, make RIP timers of RIP routers identical to each other to avoid unnecessary traffic or route
oscillation.
To configure RIP timers:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter RIP view.
rip
[
process-id
] [
vpn-instance
vpn-instance-name
]
N/A
3.
Configure values for RIP
timers.
timers
{
garbage-collect
garbage-collect-value
|
suppress
suppress-value
|
timeout
timeout-value
|
update
update-value
} *
Optional.
The default update timer, timeout
timer, suppress timer, and
garbage-collect timer are 30s,
180s, 120s, and 120s
respectively.
Configuring split horizon and poison reverse
The split horizon and poison reverse functions can avoid routing loops. If both split horizon and poison
reverse are configured, only the poison reverse function takes effect.
Enabling split horizon
The split horizon function disables an interface from sending routes received from the interface to prevent
routing loops between adjacent routers.
To enable split horizon:
Step Command

1.
Enter system view.

2.
Enter interface view.
