<Sysname> system-view
[Sysname] ospfv3 1
[Sysname-ospfv3-1] transmit-pacing interval 30 count 10
vlink-peer (OSPFv3 area view)
Use vlink-peer to configure a virtual link.
Use undo vlink-peer to remove a virtual link.
Syntax
vlink-peer router-id [ dead seconds | hello seconds | instance instance-id | ipsec-profile profile-name |
retransmit seconds | trans-delay seconds ] *
undo vlink-peer router-id [ dead | hello | ipsec-profile | retransmit | trans-delay ] *
Default
No virtual link is configured.
Views
OSPFv3 area view
Predefined user roles

Parameters
router-id: Specifies the router ID of the neighbor on the virtual link.
dead seconds: Sets the dead interval in the range of 1 to 32768 seconds. The default is 40. The dead
interval must be identical with that on the virtual link neighbor, and must be at least four times the hello
interval.
hello seconds: Sets the hello interval in the range of 1 to 8192 seconds. The default is 10. It must be
identical with the hello interval on the virtual link neighbor.
instance instance-id: Sets the instance ID of a virtual link, in the range of 0 to 255. The default is 0.
ipsec-profile profile-name: Specifies an IPsec profile by its name, a case-sensitive string of 1 to 63
characters.
retransmit seconds: Sets the retransmission interval in the range of 1 to 3600 seconds. The default is 5.
trans-delay seconds: Sets the transmission delay interval in the range of 1 to 3600 seconds. The default
is 1.
Usage guidelines
For non-backbone areas without direct connections to the backbone area or for a backbone area that
cannot maintain connectivity, you can use the vlink-peer command to create logical links. A virtual link
is similar to an interface with OSPFv3 enabled, because parameters such as hello, dead, retransmit and
trans-delay are configured in the same way.
Both ends of a virtual link are ABRs that are configured with the vlink-peer command.
For more information about IPsec profiles, see Security Configuration Guide.
Considerations on parameters:
• The smaller the hello interval is, the faster the network converges, and the more network resources
are consumed.
