Parameter
interval: Interval, in seconds, for retransmitting LSA on an interface. It ranges from 1 to
3600 and defaults to 5.
Description
Use the ospf timer retransmit command to configure the interval for LSA
retransmission on an interface.
Use the undo ospf timer retransmit command to restore the default interval value
for LSA retransmission 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 retransmission interval, this LSA will be
retransmitted.
The LSA retransmit between adjacent routers should not be set too short; otherwise,
unexpected retransmission will occur (See RFC2328).
Example
# Specify the retransmit for LSA transmission between the interface Vlan-interface 10
and the adjacent routers to 12 seconds.
