real-mac: Associates the real MAC address of the interface with the virtual IPv6 
address of the standby group.

virtual-mac: Associates the virtual MAC address with the virtual IPv6 address.

Use the vrrp ipv6 method command to set the mappings between the virtual 
IPv6 addresses and the MAC addresses of the standby groups.

Use the undo vrrp ipv6 method command to restore the default mapping.

By default, the virtual IPv6 address of the standby group is associated with MAC 
address.

Configure the mapping between the virtual IPv6 address and the MAC address 
before configuring a standby group. Otherwise, your configuration will fail.

# Associate the virtual IP address of the standby group with the real MAC address 
of the routing interface.

Use the vrrp ipv6 ping-enable command to enable users to ping the virtual IPv6 
addresses of standby groups.

Use the undo vrrp ipv6 ping-enable command to disable the virtual IPv6 
addresses of standby groups from being pinged.

By default, the virtual IP addresses of standby groups can be pinged.

Perform this configuration before configuring a standby group.

# Enable users to ping the virtual IPv6 addresses of standby groups.
