Tuning and optimizing the RIPng network
This section describes how to tune and optimize the performance of the RIPng network, as well as
applications under special network environments. Before tuning and optimizing the RIPng network,
complete the following tasks:
• Configure a network layer address for each interface.
• Configure the basic RIPng functions.
Configuring RIPng timers
You can adjust RIPng timers to optimize the performance of the RIPng network.
When adjusting RIPng timers, consider the network performance, and perform unified configurations on
routers running RIPng to avoid unnecessary network traffic or route oscillation.
To configure RIPng timers:

Optional.
The RIPng timers have the following
defaults:
• Update timer—30 seconds.
• Timeout timer—180 seconds.
• Suppress timer—20 seconds.
• Garbage-collect timer—20 seconds.
Configuring split horizon and poison reverse
If both split horizon and poison reverse are configured, only the poison reverse function takes effect.
Configuring split horizon
The split horizon function disables a route learned from an interface from being advertised through the
same interface to prevent routing loops between neighbors.
HP recommends enabling split horizon to prevent routing loops.
In frame relay, X.25 and other non-broadcast multi-access (NBMA) networks, split horizon should be
disabled if multiple VCs are configured on the primary interface and secondary interfaces to ensure
route advertisement. For detailed information, see Layer 2—WAN Configuration Guide.
