Specifying the type of MAC addresses mapped to virtual IPv6
addresses
After you specify the type of MAC addresses mapped to the virtual IPv6 address of VRRP groups
and create a VRRP group, the master in the VRRP group uses the specified type of MAC address as
the source MAC address for sending packets and uses the specified type of MAC address to answer
ND requests from hosts so that the hosts in the internal network can learn the mapping between the
IPv6 address and the MAC address.
The following types of MAC addresses are available to be mapped to the virtual IPv6 address of a
VRRP group:
•
Virtual MAC address—By default, a virtual MAC address is automatically created for a VRRP
group when the VRRP group is created, and the virtual IPv6 address of the VRRP group is
mapped to the virtual MAC address. When such a mapping is adopted, the hosts in the internal
network do not 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.
When VRRP operates in load balancing mode, a virtual IPv6 address is always mapped to a virtual
MAC address regardless of which type of MAC addresses are specified to be 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.
To specify the type of MAC addresses mapped to virtual IPv6 addresses:
Step
1. Enter system view.
2. Specify the type of MAC
addresses mapped to virtual
IPv6 addresses.
Command
system-view
vrrp ipv6 method { real-mac |
virtual-mac }
