Configuring VRRP6 Association

Configuring VRRP6 Association

VRRP6 association enables VRRP6 to detect faults in a timely manner and triggers an active/standby switchover when the master or the uplink of the master becomes faulty. VRRP6 association optimizes VRRP6 switchover and enhances network reliability.

Pre-configuration Tasks

Before configuring VRRP6 association, complete the following task:

Configuring Association Between VRRP6 and BFD to Implement a Rapid Active/Standby Switchover

Context

You can associate a VRRP6 group with a BFD session. When the BFD session status changes, BFD notifies the VRRP6 group. This process triggers a rapid active/standby switchover.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The view of the interface where a VRRP6 group is configured is displayed.

  3. 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.

    If an Ethernet interface already has Layer 2 configuration, this command fails to be executed on the interface. Before running this command on the interface, delete all the Layer 2 configuration of the interface.

    NOTE:

    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run:

    vrrp6 vrid virtual-router-id track bfd-session { session-id | session-name bfd-configure-name } [ increased value-increased | reduced value-reduced ]

    Association between VRRP6 and BFD is configured to implement a rapid active/standby switchover.

    increased value-increased: specifies the value by which the priority increases when the monitored BFD session becomes Down. The value is an integer that ranges from 1 to 255. The value 255 is reserved for the IP address owner, so the maximum value of value-increased is 254. This parameter is valid only when the VRRP6 group is in Backup state.

    reduced value-reduced: specifies the value by which the priority decreases when the monitored BFD session becomes Down. The value is an integer that ranges from 1 to 254. The lowest priority is 1. When the priority is decreased to 1, the master sends a VRRP6 Advertisement packet with priority 0. The value 0 is reserved. When the backup receives a VRRP6 Advertisement packet with priority 0, the backup becomes the master immediately. By default, the value is 10.

    NOTE:

    When setting the value by which the priority increases or decreases, ensure that the backup has higher priority than the master so that a rapid active/standby switchover is performed.

    When associating a VRRP6 group with a BFD session, note the following points:

    • During the configuration of a rapid active/standby VRRP6 switchover, to associate a VRRP6 group with a peer BFD session, you must configure peer BFD sessions on both the master and backup. If only one device is configured with a peer BFD session, the VRRP6 group status may flap.

    • If session-name bfd-configure-name is specified, the VRRP6 group can be bound to only the static BFD session with automatically negotiated discriminators.

    • If session-id is specified, the VRRP6 group can be bound to only the static BFD session.

Configuring Association Between VRRP6 and the Interface Status to Implement an Active/Standby Switchover

Context

When the uplink interface of the master becomes faulty, VRRP6 cannot detect the status change of interfaces not in the VRRP6 group, causing service interruption. You can associate a VRRP6 group with the interface status. When the monitored interface is faulty, the priority of the master is reduced. This triggers an active/standby switchover and reduces the impact of the uplink interface fault on service forwarding.

When the fault is rectified, the original master restores its priority and switches to the master to forward traffic.

NOTE:

The master and backup in the VRRP6 group must work in preemption mode. It is recommended that the preemption delay be 0 on the backup and non-0 on the master.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The view of the interface on the master where a VRRP6 group is configured is displayed.

  3. 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.

    If an Ethernet interface already has Layer 2 configuration, this command fails to be executed on the interface. Before running this command on the interface, delete all the Layer 2 configuration of the interface.

    NOTE:

    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run:

    vrrp6 vrid virtual-router-id track interface interface-type interface-number [ increase value-increased | reduce value-reduced ]

    Association between VRRP6 and the interface status is configured.

    By default, when the monitored interface goes Down, the VRRP6 priority of the device decreases by 10.

    NOTE:

    If the IPv4 protocol status on the monitored interface configured with an IPv4 address changes, the priority of the master is reduced. If the IPv6 protocol status on the monitored interface configured with an IPv6 address changes, the VRRP6 group remains unchanged.

Checking the Configuration

Procedure

  • Run the display vrrp6 [ admin-vrrp | [ interface interface-type interface-number [ virtual-router-id ] | virtual-router-id ] [ verbose ] ] command to check the VRRP6 group status and parameters.
  • Run the display vrrp6 [ interface interface-type interface-number [ virtual-router-id ] ] statistics command to check statistics about sent and received packets of the VRRP6 group.
