Creating an mVRRP Group

Procedure

1. Run system-view

   The system view is displayed.

2. Run interface interface-type interface-number

   The interface view is displayed.

3. Run admin-vrrp vrid virtual-router-id [ ignore-if-down ]

   An mVRRP group is created.

   Among multiple VRRP groups configured on two devices, the master device in a backup group has to broadcast VRRP Advertisement packets to the backup device through a user-side device. If the user-side device does not support broadcast, it cannot transparently forward VRRP Advertisement packets from the master device to the backup device. mVRRP can be enabled on interfaces directly connecting the master device to the backup device, implementing VRRP status negotiation.

   If either of the directly connected VRRP-enabled interfaces fails, the VRRP status on the other VRRP-enabled interface becomes Initialize, causing service interruptions. To prevent this issue, configure the ignore-if-down parameter in the admin-vrrp vrid command. This setting helps the other VRRP-enabled device to ignore an interface Down event and ensures proper service transmission.

   

   Adding the directly connected interfaces to an inter-board trunk for an mVRRP group is recommended, ensuring the link reliability. Do not run the shutdown command on either of the directly connected VRRP-enabled interfaces, preventing two master devices from coexisting or adversely affecting service forwarding.

4. (Optional) Run vrrp vrid virtual-router-id initialize state-hold-time timer-value

   An Initialize state hold time is configured for the mVRRP group.

   After the mVRRP group is configured to ignore an interface Down event, you can run the command.

5. Run commit

   The configuration is committed.
