Tuning and optimizing OSPF networks
You can optimize an OSPF network in the following ways:
• Change OSPF packet timers to adjust the OSPF network 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.
• Configure OSPF network management functions, such as binding OSPF MIB with a process,
sending trap information, and collecting log information.
Configuration prerequisites
Before you configure OSPF network optimization, complete the following tasks:
• Configure IP addresses for interfaces.
• Enable OSPF.
