VRRP6 Configuration

The Virtual Router Redundancy Protocol (VRRP) is a fault-tolerant protocol. IPv6-based VRRP is called VRRP for IPv6 (VRRP6). VRRP6 allows logical devices to operate separately from physical devices, improving device reliability and simplifying host configurations.

Overview of VRRP6: VRRP6 implements redundancy backup for egress gateways and ensures communication continuity and reliability.

Configuration Precautions for VRRP6

Configuring Basic VRRP6 Functions: VRRP6 works in either master/backup or load balancing mode, implementing device backup and efficient and stable data forwarding.

Configuring VRRP6 Association: This section describes how to configure VRRP6 association. If a network link fails, VRRP6 association enables a VRRP6 group to rapidly perform a master/backup VRRP6 switchover, which ensures correct service traffic forwarding.

Configuring an mVRRP6 Group: mVRRP6 is used when multiple VRRP6 groups coexist. mVRRP6 helps decrease the number of VRRP6 Advertisement packets to be sent and minimize network bandwidth consumption.

Enabling Enhanced Sending and Replication of NA Messages for a VRRP6 Group: After enhanced sending and replication of Neighbor Advertisement (NA) messages is enabled for a VRRP6 group, when a backup device in the VRRP6 group assumes the master role, it sends an NA message for each virtual IPv6 address six consecutive times. At the same time, the device replicates each NA message to be sent to each Eth-Trunk member interface if the VRRP6 group is configured on an Eth-Trunk interface or Eth-Trunk sub-interface. This ensures that downstream devices can receive the NA messages and update destination MAC addresses and outbound interfaces in time.

Maintaining a VRRP6 Group: To view VRRP6 statistics within a period of time, you are advised to clear the existing ones.

Configuration Examples for VRRP6: This section provides VRRP6 configuration examples.
