Tuning And Optimizing Ospfv3 Networks; Configuration Prerequisites; Configuring Ospfv3 Timers - HP MSR2000 series Configuration Manual

Using the filter-policy export command filters routes redistributed with the import-route command.
•
If the import-route command is not configured, executing the filter-policy export command does
not take effect.
To configure OSPFv3 route redistribution:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Specify a default cost for
redistributed routes.
4. Redistribute routes from
another protocol, or another
OSPFv3 process.
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.
•
