VLAN Q-in-Q Subinterfaces (802.1ad + 802.1q)
This example configures a service VLAN subinterface (IEEE 802.1ad) with a stacked customer VLAN subinterface (IEEE 802.1q):
- set the base interface link to
up - create a S-VLAN subinterface for VLAN ID
10 - create a C-VLAN subinterface for VLAN ID
42 - set the subinterface links state to
up - add an ipv4 address on the C-VLAN subinterface
