Prerequisites; Configuring Ospf Packet Timers - HP 4800G Series Configuration Manual

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

Before configuring OSPF network optimization, you have configured:
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 convergence speed and smaller 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.
Follow these steps to configure timers for OSPF packets:
To do...
Enter system view
Enter interface view
Specify the hello
interval
Specify the poll
interval
Specify the dead
interval
Specify the
retransmission
interval
Use the command...
system-view
interface interface-type
interface-number
ospf timer hello seconds
ospf timer poll seconds
ospf timer dead seconds
ospf timer retransmit
interval
1-33
Remarks

—
Optional
The hello interval on P2P, Broadcast
interfaces defaults to 10 seconds and
defaults to 30 seconds on P2MP and
NBMA interfaces.
Optional
The poll interval defaults to 120 seconds.
Optional
The default dead interval is 40 seconds on
P2P, Broadcast interfaces and 120
seconds on P2MP and NBMA interfaces.
Optional
The retransmission interval defaults to 5
seconds.
