Configuring OSPF network optimization
You can optimize your OSPF network as follows:
•
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 on interfaces.
•
Change the interval for SPF calculation to reduce resource consumption caused by frequent
network changes.
•
Configure OSPF authentication to meet high security requirements of some mission-critical
networks.
•
Configure OSPF network management functions, such as binding OSPF MIB with a process,
sending trap information, and collecting log information.
Prerequisites
•
IP addresses for interfaces
•
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. The
longer the interval, the lower the convergence speed and the smaller the network load.
•
Poll timer: Interval for sending hello packets to the 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 will retransmit the LSA.
