c
CAUTION: You should configure this function before creating a standby group.
Otherwise, you cannot ping the virtual IPv6 addresses of standby groups.
Configuring the
Association Between
MAC Address and
Virtual IPv6 Address
Two types of association are available between MAC address and Virtual IPv6
address:
■ Virtual IPv6 address is associated with the MAC address of virtual switch
■ Virtual IPv6 address is associated with the real MAC address of an interface
Follow these steps to configure the association between MAC address and virtual
IPv6 address:
c
CAUTION: You should configure this function before creating a standby group.
Otherwise, you cannot modify the mapping between the MAC address and the
virtual IP address.
Creating Standby Group
and Configuring Virtual
IPv6 Address
Configuration prerequisites
Before creating standby group and configuring virtual IPv6 address, you should
first configure the IPv6 address of the interface and ensure that the virtual IPv6
address to be configured is in the same network segment as the IPv6 address of
the interface.
Configuration procedure
Follow these steps to create standby group and configure its virtual IPv6 address:
c
CAUTION:
■ For Switch 8800s, the maximum number of VRRPv3 standby groups on an
interface is 16, the maximum number of virtual IP addresses in a standby group
is 16 and the maximum number of standby groups on a switch is 64.
To do... Use the command... Remarks
Enter system view system-view -
Configure the association
between MAC address and
virtual IPv6 address
vrrp ipv6 method { real-mac
| virtual-mac }
Optional
The virtual MAC address of
the standby group is
associated with the virtual
IPv6 address by default.
To do... Use the command... Remarks
Enter system view system-view -
Enter VLAN interface view interface interface-type

-
Create standby group and
configure its virtual IPv6
address
vrrp ipv6 vrid
virtual-router-id virtual-ip
virtual-address [ link-local ]
Required
No standby group is created
by default.
The first virtual IPv6 address of
the standby group must be a
link local address. Only one
link local address is allowed in
a standby group, and must be
removed the last.
