instance-id: Specifies an instance by its ID in the range of 0 to 255, The default is 0. Usage guidelines After the device sends an LSA to its neighbor, it waits for an acknowledgement. If the device receives no acknowledgement after the LSA retransmission interval elapses, it will retransmit the LSA. The LSA retransmission interval should not be too small for avoidance of unnecessary retransmissions.

instance-id
: Specifies an instance by its ID in the range of 0 to 255, The default is 0.
Usage guidelines
After the device sends an LSA to its neighbor, it waits for an acknowledgement. If the device receives no
acknowledgement after the LSA retransmission interval elapses, it will retransmit the LSA.
The LSA retransmission interval should not be too small for avoidance of unnecessary retransmissions.
Examples
# Configure the LSA retransmission interval on VLAN-interface 10 in instance 1 as 12 seconds.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospfv3 timer retransmit 12 instance 1
ospfv3 trans-delay
Use
ospfv3 trans-delay
to configure the transmission delay for an interface.
Use
undo ospfv3 trans-delay
to restore the default.
Syntax

Default
The transmission delay is 1 second.

Parameters
seconds
: Specifies the transmission delay in the range of 1 to 3600 seconds.
instance-id
: Specifies an instance by its ID in the range of 0 to 255. The default is 0.
Usage guidelines
Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change
during transmission. Therefore, it is necessary to add a transmission delay into the age time, especially
for low-speed links.
Examples
# Configure the transmission delay as 3 seconds for VLAN-interface 10 in instance 1.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospfv3 trans-delay 3 instance 1
preference
Use
preference
to specify a preference for OSPFv3 routes.
