3Com CoreBuilder 2500 - Setting Retransmit Timers; Setting Hello Timers

Configuring OSPF Interfaces 13-13
Setting Hello Timers The interface hello timer determines how often, in seconds, the interface
transmits hello packets to neighbor routers on the network. Hello packets
notify other routers that the sending router is still active on the network.
If a router does not send hello packets for a period of time specified by
the dead interval, the router is considered inactive by its neighbors. See
“Setting Dead Intervals” on page 13-14 for more information.
Default The default value for the hello timer is 10 seconds.
CAUTION: Set the hello timer to the same value for all routers on the
network segment because they are in the same area.
To set the hello timer:
1 From the top level of the Administration Console, enter:
ip ospf interface hello
2 Enter an IP interface.
3 Enter the hello timer value, in seconds.
Allowable values:
1 through 65535.
Setting
Retransmit Timers
This command specifies the LSA retransmit interval for each interface.
You set the retransmit interval in seconds.
Default The default value for the retransmit timer is 5 seconds.
To set the retransmit time:
1 From the top level of the Administration Console, enter:
ip ospf interface retransmit
2 Enter an IP interface.
3 Enter the LSA retransmit time, in seconds.
Allowable values:
1 through 65535.
