Specifying The Type Of Mac Addresses Mapped To Virtual Ip Addresses; Specifying The Vrrp Control Vlan - HPE FlexNetwork HSR6800 series Configuration Manual

Specifying the type of MAC addresses mapped to virtual IP
addresses
You can configure VRRP in standard mode to map real or virtual MAC addresses to the virtual IP
addresses of VRRP groups, so the master in a VRRP group uses the specified type of MAC address
as the source MAC address for sending packets and answering ARP requests.
•
Virtual MAC to virtual IP mapping—By default, a virtual MAC address is automatically
assigned when a VRRP group is created, and the virtual IP address of the VRRP group is
mapped to the virtual MAC address. In this mapping approach, the hosts do not need to update
the gateway IP and MAC mapping entry when the master changes.
•
Real MAC address of an interface—If a VRRP group has an IP address owner, configure real
MAC to virtual IP mapping to avoid the problem of one IP address mapped to two MAC
addresses (the real and the virtual). In this approach, the virtual IP address of the VRRP group
is mapped to the real MAC address of the IP address owner, and all packets from hosts are
forwarded to the IP address owner.
If VRRP groups with the same ID are created on multiple interfaces, and the VRRP advertisements
of these VRRP groups are to be sent across a QinQ network, Hewlett Packard Enterprise
recommends that you use real MAC to virtual IP mapping to guarantee successful transmission of
the VRRP advertisements.
When VRRP operates in load balancing mode, the address mapping setting does not take effect,
and virtual IP addresses are always mapped to virtual MAC addresses.
Specify the type of the MAC addresses mapped to the virtual IP addresses before creating a VRRP
group. You cannot change the address mapping setting after a VRRP group is created.
To specify the type of MAC addresses mapped to virtual IP addresses:
Step
1. Enter system view.
2. Specify the type of MAC
addresses mapped to virtual
IP addresses.

Specifying the VRRP control VLAN

With VLAN termination, after a port receiving a VLAN packet, it removes its VLAN tags and then
forwards it at Layer 3 or processes it in other ways. VLAN termination includes the following
categories:
•
Unambiguous termination—Terminates VLAN packets from a specified VLAN only. In other
words, after receiving a packet from the specific VLAN, a port configured with unambiguous
VLAN termination removes its VLAN tag.
•
Ambiguous termination—Terminates VLAN packets from multiple VLANs whose VLAN IDs
are in the specified range. In other words, after receiving a packet from a VLAN in the specified
range, a port configured with ambiguous VLAN termination removes its VLAN tag.
By default, an ambiguous termination-enabled Layer 3 subinterface or VLAN interface drops
broadcast and multicast packets they receive, instead of transmitting them.
You can enable a Layer 3 Ethernet subinterface, or a VLAN interface configured with ambiguous
termination to transmit broadcast/multicast packets within all VLANs whose VLAN packets are
configured to be terminated by the subinterface or VLAN interface.
