R3721-F3210-F3171-HP High-End Firewalls Network Management Configuration Guide-6PW101

388
• 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 tune and optimize OSPF networks, 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. 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:

3. Specify the hello interval.
ospf timer hello seconds
Optional.
The hello interval defaults to
10 seconds on P2P and
broadcast interfaces, and
defaults to 30 seconds on
P2MP and NBMA interfaces.
4. Specify the poll interval.
ospf timer poll seconds
Optional.
The poll interval defaults to
120 seconds.
5. Specify the dead interval.
ospf timer dead seconds
Optional.
The default dead interval is 40
seconds on P2P and broadcast
interfaces and 120 seconds
on P2MP and NBMA
interfaces.
6. Specify the retransmission
interval
ospf timer retransmit interval
Optional.
The retransmission interval
defaults to 5 seconds.
