Configuring Ospfv3 Route Redistribution; Tuning And Optimizing Ospfv3 Networks - HPE 5800 Series Configuration Manual

Configuring OSPFv3 route redistribution

When you configure OSPFv3 route redistribution, follow these guidelines:
•
Executing the import-route or default-route-advertise command on a router makes it become
an ASBR.
•
You can only inject and advertise a default route by using the default-route-advertise
command.
•
Because OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised;
you must filter redistributed routes first. Routes that are not filtered out can be advertised in
LSAs.
•
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
Enter system view.
1.
Enter OSPFv3 view.
2.
Specify a default cost for

redistributed routes.
Redistribute routes from

another protocol or another
OSPFv3 process.
Inject a default route.
5.
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 over-loaded due to frequent network
changes.
For a broadcast network, you can configure DR priorities for interfaces to affect DR and BDR
election.
After an interface is disabled from sending OSPFv3 packets, other routers cannot obtain any
information from the interface.
