Creating A Vrrp Group And Configuring A Virtual Ipv6 Address - HP A5830 series Configuration Manual

need to update the mapping between the IPv6 address and the MAC address when the master
changes.
Real MAC address of an interface—In case that an IP address owner exists in a VRRP group, if the
•
virtual IPv6 address is mapped to the virtual MAC address, two MAC addresses are mapped to
one IPv6 address. To avoid such as problem, map the virtual IPv6 address of the VRRP group to the
real MAC address of an interface to forward the packets from a host to the IP address owner.
To specify the type of MAC addresses mapped to virtual IPv6 addresses:
To do...
• Enter system view
• specify the type of MAC
addresses mapped to virtual
IPv6 addresses
Specify the type of the MAC addresses mapped to the virtual IPv6 addresses before creating a VRRP
group. Otherwise, you cannot change the type of the MAC addresses mapped to virtual IPv6 addresses.

Creating a VRRP group and configuring a virtual IPv6 address

When creating a VRRP group, configure a virtual IPv6 address for the VRRP group. You can configure
multiple virtual IPv6 addresses for a VRRP group.
A VRRP group is created automatically when you specify the first virtual IPv6 address for the VRRP
group. If you specify another virtual IPv6 address for the VRRP group later, the virtual IPv6 address is
added to the virtual IPv6 address list of the VRRP group.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IPv6 address on an interface, configure an IPv6
address for the interface and make sure that it is in the same network segment as the virtual IPv6 address
to be configured.
Configuration procedure
To create a VRRP group and configure its virtual IPv6 address:
To do...
• Enter system view
• Enter the specified interface
view
• Create a VRRP group and
configure its virtual IPv6
address, which is a link
local address
Use the command...
system-view
vrrp ipv6 method { real-mac |
virtual-mac }
Use the command...
system-view
