Technical Tip: Creating VDOM Links in Virtual Clusters

All supported versions of FortiGate.

As per FortiOS' design: in a virtual clustering configuration, inter-VDOM links can only be configured between virtual domains (VDOMS) that are in the same virtual cluster. A vdom-link cannot be configured between the VDOMs in different virtual clusters.

If vcluster1 and vcluster2 are configured, it is possible to create VDOM links in either vcluster1 or vcluster2 by specifiying this upon creating the VDOM link using the vcluster keyword.

The FortiGate unit must have VDOM and HA modes enabled. It is also necessary to enable multiple vclusters.

config system vdom-link

edit vlink_1

set vcluster vcluster2

next

edit vlink_2

set vcluster vcluster2

end
