3com MSR 20-20 참조 매뉴얼

Use the undo ospf timer retransmit command to restore the default.

The interval defaults to 5s.

After sending a LSA, an interface waits for an acknowledgement packet. If the 
interface receives no acknowledgement when the retransmit interval elapses, it 
will retransmit the LSA.

The retransmit interval should not be so small to avoid unnecessary 
retransmissions.

This configuration is not supported on the NULL interface.

# Set the LSA retransmit interval to 8 seconds.

seconds: LSA transmit delay time in seconds, in the range 1 to 3600.

Use the ospf trans-delay command to set the LSA transmit delay time on an 
interface.

Use the undo ospf trans-delay command to restore the default.

The delay time defaults to 1s.

Each LSA in the LSDB has an age (incremented 1 by a second), but a LSA is not 
aged out during transmission. It is necessary to add a transmit delay into its age 
time, which is important for transmission on low speed networks.

This configuration is not supported on the NULL interface.

# Set the LSA transmit delay time to 3 seconds on the current interface.
