Enabling a QinQ termination-enabled
interface/subinterface to transmit broadcast and
multicast packets
By default, an ambiguous QinQ termination-enabled subinterface or VLAN interface drops broadcast
and multicast packets it receives, instead of transmitting them.
You can enable an ambiguous QinQ termination-enabled Layer 3 Ethernet/aggregate subinterface or
VLAN interface to transmit broadcast and multicast packets.
To enable an ambiguous QinQ termination-enabled Layer 3 Ethernet/aggregate subinterface or VLAN
interface to transmit broadcast and multicast packets:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Enable the QinQ
termination-enabled
subinterface or VLAN interface
to transmit broadcast and
multicast packets.

Remarks
Optional.
By default, the TPID value in the
outer VLAN tag is 0x8100.
If the interface receives and sends
QinQ packets, the TPID value in
the inner VLAN tag of packets is
always 0x8100, and is not
configurable.
