Command Manual – IPv6 Routing
H3C S7500E Series Ethernet Switches Chapter 3 IPv6 OSPFv3 Configuration Commands
3-35
Parameters
seconds: Transmission delay in seconds, ranging from 1 to 3600.
instance-id: Instance ID of an interface, in the range of 0 to 255, with the default as 0.
Description
Use the ospfv3 trans-delay command to configure the transmission delay for an
interface with an instance ID.
Use the undo ospfv3 trans-delay command to restore the default.
The transmission delay defaults to 1s.
As LSAs are aged in the LSDB (incremented by 1 every second) but not aged on
transmission, it is necessary to add a delay time to the age time before sending a LSA.
This configuration is important for low-speed networks.
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
