Description

This article gives a tip on configuring an IPv6 address on an inter VDOM link.

Scope

FortiOS 5.2.x

Solution

Only IPv4 addresses can be configured on an inter VDOM link using the GUI.  Configuring an IPv6 address on an inter VDOM link interface can only be done via the CLI.

Assuming an inter VDOM link ‘VDOM1Vlnk’ composed of two interfaces 'VDOM1Vlnk0' and 'VDOM1Vlnk1', configuring an IPv6 address on the 'VDOM1Vlnk0' interface can then be done via the CLI, by editing the 'VDOM1Vlnk0' configuration, and setting the IPv6 part that is located in the ‘config ipv6’ command section.  The same logic applies to 'VDOM1Vlnk1' interface.

# config global
(global) # config system interface
(interface) # edit VDOM1Vlnk0
(VDOM1Vlnk0) # config ipv6
(ipv6) # get
ip6-mode            : static
ip6-allowaccess     : ping
ip6-address         : 2a02:8400:220::15/125
ip6-extra-addr:
ip6-send-adv        : disable
autoconf            : disable
dhcp6-relay-service : disable
(ipv6) #
