3. Redistribute
route.
Setting tags for redistributed routes
Perform this task to set tags for redistributed routes to identify information about protocols. For
example, when redistributing IPv6 BGP routes, OSPFv3 uses tags to identify AS IDs.
To set a tag for redistributed routes:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Set a tag for redistributed
routes.

Tuning and optimizing OSPFv3 networks

This section describes configurations of OSPFv3 timers, interface DR priority, and the logging of
neighbor state changes.

Configuration prerequisites

Before you tune and optimize OSPFv3 networks, perform the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring
nodes.
•
Enable OSPFv3.

Setting OSPFv3 timers

Step
1. Enter system view.
2. Enter interface view.
3. Set the hello interval.
4. Set the dead interval.
5. Set the poll interval.
