Tuning and optimizing OSPF networks
You can optimize an OSPF network in the following ways:
• 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, complete the following tasks:
• Configure IP addresses for interfaces.
• Enable OSPF.
Configuring OSPF packet timers
You can configure the following timers on OSPF interfaces as needed.
• Hello timer—Interval for sending hello packets. It must be identical on OSPF neighbors.
