802.1Q Tunneling - Cisco Community

The official names of these configurations are an 802.1q Tunnel and an EtherChannel over an 802.1q Tunnel. I call them the Tube and the Rainbow. It's just a mnemonic that I use to help me remember the diagrams and how to configure them. Let's start with the basic 802.1q Tunnel (aka The Tube or more commonly QinQ tunneling). 802.1Q VLAN with mixed Cisco HP switches - Hewlett Packard Mixing Cisco and HP Networking switches together with 802.1Q is not an issue, it all works very well. 802.1Q is a standard. Now, what is different is the terminology: on Cisco, assigning ports to vlans that are 802.1Q is called a "trunk" port. HP (ProCurve switches) defines a port in a vlan supporting 802.1Q … Q Tunneling - CCIE - Cisco Certified Expert The 802.1Q tunneling expands VLAN space by using a VLAN-in-VLAN hierarchy and tagging the tagged packets. A port configured to support 802.1Q tunneling is called a tunnel port. When you configure tunneling, you assign a tunnel port to a VLAN that is dedicated to tunneling. Each customer requires a separate VLAN, but that VLAN supports all of Connecting two segments through Q n Q tunneling - YouTube

This can be called VLAN stacking, Q-in-Q tunnels, or dot1q tunnels. The ‘Q-in-Q’ comes from the 802.1Q VLAN specification. Q-in-Q also helps providers to save money. When a provider gets a new customer, they have to provide a port into their core or aggregation network.

2 Adaptation, Layering, and Tunneling - Grotto Networking The multiple spanning tree protocol (MSTP) feature in 802.1Q allows us to assign different spanning trees to different VLANs. In our example network we could come up with different trees for the orange and blue VLANs as shown in Figure 18 where the different link colors are used to denote the two different trees in use and the the VLANs using them. Configuring 802.1Q and Layer 2 Protocol Tunneling A port configured to support 802.1Q tunneling is called a tunnel port. When you configure tunneling, you assign a tunnel port to a VLAN ID that is dedica ted to tunneling. Each customer requires a separate service provider VLAN ID, but that service provider VLAN ID supports VLANs of all the customers.
