Excluding interfaces in an OSPF area from the base topology

Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Exclude interfaces from the
base topology.

Tuning and optimizing OSPF networks

You can use one of the following methods to optimize an OSPF network:
•
Change OSPF packet timers to adjust the convergence speed and network load. On low-speed
links, consider the delay time for sending LSAs.
•
Change the SPF calculation interval to reduce resource consumption caused by frequent
network changes.
•
Configure OSPF authentication to improve security.

Configuration prerequisites

Before you configure OSPF network optimization, perform the following tasks:
•
Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.
