Configuring an Interface for IPv6 Static Mode

Static mode provides user a way to assign static IPv6 address as opposed to an auto-assigned address. Using

static mode, the IPv6 interface can still listen for Router Advertisements and learn an autonomous address from

the appropriate prefix option. Static Mode does not disturb the running of Stateless Address Autoconfiguration

on IPv6 interface unless the user manually disables it.

Three types of IPv6 address are possible to assign under this mode:

  • Automatic Address

  • Autonomous Address

  • Static Address

To configure an interface for a static IPv6 address

  1. Navigate to Network > System > Interfaces > Interfaces Settings.

  2. On the Interfaces Settings page, click IPv6.

  3. Hover over an interface that you want to configure for an IPv6 address and click the Edit icon. The Edit Interface dialog box is displayed.

    The zone assignment for interfaces must be configured on the IPv4 addressing page. To modify the zone assignment for an IPv6 interface, click IPv4, modify the zone for the interface, and then return to the IPv6 interface page.

  4. In the IP Assignment drop-down menu, select Static.

  5. Enter the IPv6 Address for the interface.

  6. Enter the Prefix Length for the address.

  7. If this is the primary WAN interface, enter the IPv6 address of the Default Gateway. If this is not the primary WAN interface, any Default Gateway entry is ignored, so you can leave this as ::. (The double colon is the abbreviation for an empty address, or 0:0:0:0:0:0:0:0.).

  8. If this is the primary WAN interface, enter up to three DNS Server IPv6 addresses. Again, if this is not the primary WAN interface, any DNS Server entries are ignored.

  9. Select Enable Router Advertisement to make this an advertising interface that distributes network and prefix information.

  10. Select Advertise Subnet Prefix of IPv6 Primary Static Address to add a default prefix into the interface advertising prefix list. This prefix is the subnet prefix of interface IPv6 primary static address. This option helps all hosts on the link stay in the same subnet.

  11. Click OK.
