802.1Q (Q-in-Q) BPDU tunneling The service provider can give the customers an infrastructure to run various Layer 2 protocols and connect to all geographically-separated sites. In Q-in-Q BPDU tunneling, a customer packet transferred through the service provider network is tagged twice (except for untagged customer traffic which has only one

GTACKnowledge - What is Q-in-Q or 802.1Q tunneling? 802.1Q tunneling (aka Q-in-Q) is a technique often used by Metro Ethernet providers as a layer 2 VPN for customers. 802.1Q (or dot1q) tunneling is pretty simple. The provider will put a 802.1Q tag on all the frames that it receives from a customer with a unique VLAN tag. day 271 - LAB: 802.1q tunneling (q-in-q). VLOG: keeping up Aug 26, 2018 Configuration Guide 1) Configure 802.1Q VLAN and basic VLAN-VPN. 2) Configure VLAN mapping. Configuration Guidelines Before you start, configure 802.1Q VLAN and the basic VLAN-VPN. Configure 802.1Q VLAN based on network requirements. Besides, VLAN mapping entries work only after you have set VPN up-link ports and VPN ports in the basic VLAN-VPN configuration 802.1Q Encapsulation Explained - YouTube

That Nexus is only capable of tunneling CDS, STP and VTP. EoMPLS tunnels all (e.g. 802.1x) without modification to the destination mac-address.

The IEEE 802.1Q Tunneling feature is designed for service providers who carry traffic of multiple customers across their networks and are required to maintain the VLAN and Layer 2 protocol configurations of each customer without impacting the traffic of other customers. IEEE 802.1Q Tunnel Ports in a Service Provider Network

802.1ad is a networking standard that supports Q-in-Q networks by allowing multiple 802.1Q tags in an Ethernet frame. Each interface in a customer network is assigned to a customer-VLAN (c-V LAN). Packets in c-VLANs contain 802.1q tags that switch traffic within the network. c … QinQ: IEEE 802.1Q Tunneling | Router Jockey Apr 19, 2012 CCIE Study Notes: 802.1q Tunnels
