The technique is also known as provider -bridging, Stacked VLANs, or simply QinQ or Q-in-Q. "Q-in-Q" can for supported -devices apply to C-tag stacking on C-tag (Ethernet Type = 0x8100). - -The original 802.1q specification allows a single Virtual Local Area Network -(VLAN) header to be inserted into an Ethernet frame. QinQ allows multiple -VLAN tags to be inserted into a single frame, an essential capability for -implementing Metro Ethernet network topologies. Just as QinQ extends 802.1Q, -QinQ itself is extended by other Metro Ethernet protocols. - -In a multiple VLAN header context, out of convenience the term "VLAN tag" or -just "tag" for short is often used in place of "802.1Q VLAN header". QinQ -allows multiple VLAN tags in an Ethernet frame; together these tags constitute -a tag stack. When used in the context of an Ethernet frame, a QinQ frame is a -frame that has 2 VLAN 802.1Q headers (double-tagged). - -In VyOS the terms **vif-s** and **vif-c** stand for the ethertype tags that -are used: - -The inner tag is the tag which is closest to the payload portion of the frame. -It is officially called C-TAG (customer tag, with ethertype 0x8100). The outer -tag is the one closer/closest to the Ethernet header, its name is S-TAG -(service tag with ethertype 0x88a8). - -Configuration commands: - -.. code-block:: none - - interfaces - ethernet <eth[0-999]> - address <ipv4> - address <ipv6> - description <txt> - disable - ip - <usual IP options> - ipv6 - <usual IPv6 options> - vif-s <[0-4096]> - address <ipv4> - address <ipv6> - description <txt> - disable - ip - <usual IP options> - ipv6 - <usual IPv6 options> - vif-c <[0-4096]> - address <ipv4> - address <ipv6> - description <txt> - disable - ip - <usual IP options> - ipv6 - <usual IPv6 options> - - -Example: - -.. code-block:: none - - set interfaces ethernet eth0 vif-s 333 - set interfaces ethernet eth0 vif-s 333 address 192.0.2.10/32 - set interfaces ethernet eth0 vif-s 333 vif-c 777 - set interfaces ethernet eth0 vif-s 333 vif-c 777 address 10.10.10.10/24 - -.. _802.1ad: https://en.wikipedia.org/wiki/IEEE_802.1ad
