Creating a VRRP6 Group

Creating a VRRP6 Group

Context

VRRP6 virtualizes multiple devices into one gateway without changing the networking, and uses the virtual gateway's IP address as the default gateway address to implement next-hop gateway backup. After a VRRP6 group is configured, traffic is forwarded through the master. When the master fails, a new master is selected among backups to forward traffic. This ensures device-level reliability.

If load balancing is required in addition to gateway backup, configure two or more VRRP6 groups on an interface in single-gateway load balancing mode or multi-gateway load balancing mode.

Procedure

  1. Create a VRRP6 group working in active/standby mode.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      ipv6

      The IPv6 function is enabled.

      By default, a device is disabled from forwarding IPv6 unicast packets.

    3. Run:

      interface interface-type interface-number

      The interface view is displayed.

    4. (Optional) On an Ethernet interface, run undo portswitch

      The interface is switched to Layer 3 mode.

      By default, an Ethernet interface works in Layer 2 mode.
      NOTE:

      Only the S5720HI, S5720EI, S6720EI, and S6720S-EI support switching between Layer 2 and Layer 3 modes.

    5. Run:

      ipv6 enable

      IPv6 is enabled on the interface.

      By default, the IPv6 function is disabled on an interface.

    6. Run:

      ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }

      An IPv6 address is configured for the interface.

    7. Run:

      vrrp6 vrid virtual-router-id virtual-ip virtual-ipv6-address [ link-local ]

      A VRRP6 group is created, and a virtual IPv6 address is assigned to the VRRP6 group.

      By default, no VRRP6 group is created.

      The first virtual IPv6 address of a VRRP6 group must be a link-local address.

  2. Create VRRP6 groups working in multi-gateway load balancing mode.

    If VRRP6 groups need to work in multi-gateway load balancing mode, repeat the Create a VRRP6 group working in master/backup mode steps to configure multiple VRRP6 groups on the interface and assign different VRIDs to them.
