Complete these tasks to configure VRRP for IPv6:
Task
"Enabling Users to Ping Virtual IPv6 Addresses" on page 1984
"Configuring the Association Between Virtual IPv6 Address and MAC
Address" on page 1984
"Creating Standby Group and Configuring Virtual IPv6 Address" on page

You can configure whether the master router responds to the received ICMPv6
echo requests, that is, whether the virtual IPv6 address of a standby group can be
successfully pinged.
Follow these steps to enable a user to successfully ping the virtual IPv6 addresses
of standby groups:
To do...
Enter system view
Enable a user to ping virtual
IPv6 address of the standby
group
c
CAUTION: You should configure this function before creating a standby group.
Otherwise, you cannot ping the virtual IPv6 addresses of standby groups.
After the virtual IPv6 address of a standup group is associated with the MAC
address, the master router takes the configured MAC address as the source MAC
address of the packets to be sent, so that the hosts in the internal network can
learn the association between the IPv6 address and the MAC address and thus
forward the packets to be forwarded to the other network segments to the master
router properly.
There are two types of association between virtual IPv6 address and MAC address:
Virtual IPv6 address is associated with virtual router MAC address
■
By default, a MAC address is created for a standby group after the standby group
is created, and the virtual IPv6 address is associated with the virtual MAC address.
With such association adopted, the hosts in the internal network need not update
the association between IPv6 address and MAC address when the master router
changes.
Virtual IPv6 address is associated with real MAC address of the interface
