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, you must 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.
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. The longer
the interval, the lower the convergence speed, and the smaller the network load.
• 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 receives no hello packet from the neighbor, it
declares the neighbor is down.
• LSA retransmission timer—Interval within which if the interface receives no acknowledgement
packets after sending a LSA to the neighbor, it retransmits the LSA.
To configure timers for OSPF packets:
