Tuning and optimizing OSPF networks
You can optimize your 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.
•
Configure OSPF basic functions.
•
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.
•
•
Poll timer—Interval for sending hello packets to a neighbor that is down on the NBMA network. The
poll interval is at least four times the hello interval.
