Using VLANs to add more accelerated inter-VDOM links
You can add VLAN interfaces to the NPU VDOM link interfaces to create inter-VDOM links between more VDOMs. For the links to work, the VLAN interfaces must be added to the same NPU VDOM link interface, must be on the same subnet, and must have the same VLAN ID.
For example, to accelerate inter-VDOM traffic between VDOMs named Marketing and Engineering using VLANs with VLAN ID 100, go to System > Network > Interfaces and select Create New to create the VLAN interface associated with the Marketing VDOM:
| Name | Marketing-link |
| Type | VLAN |
| Interface | npu0_vlink0 |
| VLAN ID | 100 |
| Virtual Domain | Marketing |
| IP/Network Mask | 172.20.120.12/24 |
Create the VLAN associated with Engineering VDOM:
| Name | Engineering-link |
| Type | VLAN |
| Interface | npu0_vlink1 |
| VLAN ID | 100 |
| Virtual Domain | Engineering |
| IP/Network Mask | 172.20.120.22/24 |
Or do the same from the CLI:
config system interface
edit Marketing-link
set vdom Marketing
set ip 172.20.120.12/24
set interface npu0_vlink0
set vlanid 100
next
edit Engineering-link
set vdom Engineering
set ip 172.20.120.22/24
set interface npu0_vlink1
set vlanid 100
end
