For subinterfaces configured with ambiguous Dot1q termination, this type of control VLAN
should be specified.
 Specifying both inner and outer VLAN tags:
For subinterfaces configured with ambiguous QinQ termination, this type of control VLAN should
be specified.
You need to specify a control VLAN only for a Layer 3 Ethernet subinterface and Layer 3 aggregation
subinterface configured with ambiguous VLAN termination.
When VRRP operates in load balancing mode, you cannot specify the VRRP control VLAN.
If you specified the VRRP control VLAN, to update MAC address entries on devices in the VLAN
terminated ambiguously after an active/standby switchover, use the arp send-gratuitous-arp
command to enable the routers in the VRRP group to periodically send gratuitous ARP packets. For
more information about the arp send-gratuitous-arp command, see Layer 3—IP Services Command
Reference.
For more information about VLAN termination, see Layer 2—LAN Switching Configuration Guide.
To specify the VRRP control VLAN:
Step
Command
Remarks
1. Enter system view.
system-view
N/A
2. Enter interface view.
 Enter Layer 3 Ethernet
subinterface view:
interface interface-type
interface-number.subnumb
er
 Enter Layer 3 aggregation
subinterface view:
interface
route-aggregation
interface-number.subnumb
er
Use either command.
3. Specify a VRRP control
VLAN.
 Specify a VRRP control
VLAN for the subinterface
configured with
ambiguous Dot1q
termination:
vrrp dot1q vid vlan-id
 Specify a VRRP control
VLAN for the subinterface
configured with
ambiguous QinQ
termination:
vrrp dot1q vid vlan-id
secondary-dot1q
secondary-vlan-id
Use either command.
By default, no VRRP control VLAN is
specified for the subinterface
configured with VLAN termination.
That is, the master sends VRRP
advertisements within all VLANs
whose VLAN packets are configured
to be terminated by the subinterface.
