Creating Standby Group
and Configuring Virtual
IPv6 Address
c
When an IP address owner exists in a standby group, if you associate the virtual
IPv6 address with the virtual MAC address, two MAC addresses are associated
with an IPv6 address. In this case, you can associate the virtual IPv6 address of the
standby group with the real MAC address, so that the packets from a host is
forwarded to the IP address owner according the real MAC address.
Follow these steps to configure the association between MAC address and virtual
IPv6 address:
To do...
Enter system view
Configure the association
between virtual IPv6 address
and MAC address
CAUTION: You should configure this function before creating a standby group.
Otherwise, you cannot modify the mapping between the virtual IPv6 address and
the MAC address.
You need to configure a virtual IPv6 address for a standby group when creating
the standby group. A VRRP standby group is created automatically when you
specify the first virtual IPv6 address for the standby group. If you specify a virtual
IPv6 address for the standby group later, the virtual IPv6 address is only added to
the virtual IPv6 address list of the VRRP standby group.
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:
To do... Use the command...
Enter system view system-view
Enter the specified interface interface-type
interface view interface-number
Create standby vrrp ipv6 vrid
group and configure virtual-router-id
its virtual IPv6 virtual-ip virtual-address
address [ link-local ]
CAUTION:
The maximum number of standby groups on an interface is 16 and the
■
maximum number of virtual IPv6 addresses in a standby group is 10.
Use the command...
system-view
vrrp ipv6 method
{ real-mac | virtual-mac }
Remarks
-
-
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.

Remarks
-
Optional
The virtual MAC address of
the standby group is
associated with the virtual
IPv6 address by default.
