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. Adding a transmission delay into the age time is important in low speed
networks.
Examples
# Set the transmission delay to 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
