Tuning And Optimizing Ospfv3 Networks; Configuration Prerequisites; Configuring Ospfv3 Timers - HP 6125G Configuration Manual

Step
5. Inject a default route.
6. Filter redistributed routes.

Tuning and optimizing OSPFv3 networks

This section describes configurations of OSPFv3 timers, interface DR priority, MTU check ignorance for
DD packets, and disabling interfaces from sending OSPFv3 packets.
The following are OSPFv3 timers:
• Packet timer—Specified to adjust topology convergence speed and network load.
LSA delay timer—Specified especially for low-speed links.
•
SPF timer—Specified to protect networks from being overloaded due to frequent network changes.
•
For a broadcast network, you can configure DR priorities for interfaces to affect DR or BDR election.
After an interface is disabled from sending OSPFv3 packets, other routers cannot obtain any information
from the interface.

Configuration prerequisites

Before you tune and optimize OSPFv3 networks, complete the following tasks:
Enable IPv6 packet forwarding.
•
Configure OSPFv3 basic functions.
•

Configuring OSPFv3 timers
