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.
• Enable OSPF.
Setting OSPF timers
An OSPF interface includes the following timers:
• 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.
• Dead timer—Interval within which if the interface does not receive any hello packet from the
neighbor, it declares the neighbor is down.
