Technical Note: OSPFv3 (OSPF for IPv6) configuration example

Scope

FortiGate v6.0.6.

Solution

Changing vdom-link type to Ethernet (default ppp) solves the issue.

config system vdom-link
    edit "vdom_link"
        set type ethernet
    next
end

Note:

It would not be possible to change the type of VDOM link in v7.2.x and later firmware. To change the type, delete then re-create the VDOM link from the CLI and set the type to 'ethernet'.
