Ospf Trans-Delay - Huawei Quidway S3900 series Command Manual

Command Manual – Routing Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
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.

3.1.44 ospf trans-delay

Syntax
ospf trans-delay seconds
undo ospf trans-delay
View
Interface view
Parameter
seconds: LSA transmission delay on an interface. It ranges from 1 to 3,600 and defaults
to 1 (in seconds).
Description
Use the ospf trans-delay command to configure the LSA transmission delay on an
interface.
Use the undo ospf trans-delay command to restore the default LSA transmission
delay on an interface.
LSA ages in the "link state database" (LSDB) of the router as time goes by (1 added
every second), but it does not age during network transmission. Therefore, it is
necessary to add a period of time set by this command to the aging time of LSA before
transmitting it.
