Parameter
interval: Interval in seconds for re-transmitting LSA on an interface. It ranges from
1 to 65,535. The default value is 5 seconds.
Description
Use the ospf timer retransmit command to configure the interval for LSA
re-transmitting on an interface.
Use the undo ospf timer retransmit command to restore the default interval
value for LSA re-transmitting on the interface.
If a router running OSPF transmits a "link state advertisement" (LSA) to the peer, it
needs to wait for the acknowledgement packet from the peer. If no
acknowledgement is received from the peer within the LSA retransmit, this LSA
will be re-transmitted. This command can change the interval of re-transmitting
LSA. However, according to RFC2328, the LSA retransmit between adjacent
routers should not be set too short. Otherwise, unexpected re-transmission will be
caused.
