Have a number of receiving vlans (t) on an interface, all of them should be tunneled with dot1q expect one vlan. This vlan is for multicast and therefor should not have an additional tag. Have only found solutions where the entire interface is tunneled.
Nov 4, 2019 How to configure Q-in-Q Tunneling in Cisco. Q-in-Q Tunneling is to allow service providers or hosting provider or data center, 4096 VLAN inside of each one of 4096 VLAN. This is really useful and easy to implement. Before going to the configuration part, lets discuss the benefits of q-in-q tunnel.
A Q-in-Q VLAN tunnel enables a service provider to segregate the traffic of different customers in their infrastructure, while still giving the customer a full range of VLANs for their internal use by adding a second 802.1Q tag to an already tagged frame. This section includes the following topics: Q-in-Q Tunneling, page 9-1.
Solved: Hello there, On nexus 3064 I can do Q-in-Q with following config: nterface g0/10 switchport switchport mode dot1q-tunnel switchport access vlan 222 but I don't know how to do many Q-in-Q incoming tunnels on one interface. I receive VLAN.
Beginner. 11-06-2006 09:29 AM. Hi, I would like to be sure I understand Q-in-Q, and especially the configuration of this feature... I understand that the ISP add a 802.1q tag for each customer. We can say that 1 customer = 1 vlan? So when I configure the switch like this: nterface FastEthernet1/0/3. description CustomerA=vlan103.
802.1Q tunneling (aka Q-in-Q) is often used by Metro Ethernet providers as a layer 2 VPN for customers. 802.1Q (or dot1q) tunneling is pretty simplethe provider will put an 802.1Q tag on all the frames that it receives from a customer with a unique VLAN tag.

. Note. Q-in-Q is supported on port channels. To configure a port channel as an asymmetrical link, all ports in the port channel must have the same tunneling configuration. Using the 802.1Q tunneling feature, service providers can use a single VLAN to support customers who have multiple VLANs.

Q-in-Q Tunneling. tunneling expands the 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.

Options. 05-16-2009 11:01 AM. Hello David, 802.1Q tunneling works well to emulate a point to point link between customer switches ports. In order for the L2 SP to support a customer side etherchannel one customer vlan for each member link is needed.
1. I have a scenario where I have 3 service vlans (10,20,30) from a trunk port and need to brige our customer vlans (100,200,300,400) between all the service vlans. I need to do it all in the same switch (cat6504e s72033_rp-ADVENTERPRISEK9-M, Version 15.1 (2)SY2, RELEASE SOFTWARE (fc3)).
