VRRPv3 Support for IPv6 OSPFv3

To use OSPFv3 with VRRPv3, you must enable the option Use Virtual Address on the applicable interfaces.

If the configured interface is part of the VRRP Master virtual router, then OSPFv3 runs on the interface.

When you enable the Use Virtual Address option, OSPFv3 uses the VRRPv3 virtual link-local address for the interface as the source of its control packets. This cannot be the automatically configured link-local address - that is, you must change the link-local address for the interface to something other than the default.

VRRP installs the link-local address only on the VRRP Master, so OSPFv3 runs only on that router. If a VRRP failover occurs, VRRPv3 installs the link-local address on the new Master, and OSPFv3 starts running on that system. Because OSPFv3 runs on one router at a time, there is no synchronization of OSPFv3 state between the VRRP group members.

Important - You must configure the same link-local address on all the routers in the VRRP group.

To configure this option in Gaia Portal:

  1. From the left navigation tree, click Advanced Routing > IPv6 OSPF

  2. In the Interfaces section, select the interface.

  3. Click Edit.

  4. Select the Use Virtual Address option.

  5. Click Save.

See Configuring IPv6 OSPFv3 Interfaces in Gaia Portal.

To configure this option in Gaia Clish:

  1. Connect to the command line.

  2. Log in to Gaia ClishClosed The name of the default command line shell in Check Point Gaia operating system. This is a restricted shell (role-based administration controls the number of commands available in the shell)..

  3. Configure the interface:

    set ipv6 ospf3 [instance {<1-65535> | default}] interface <Name of Interface> virtual-address {off | on}

  4. Save the configuration:

    save config
