tunnels and Layer 2 protocol tunneling on Cisco NXOS devices QinQ tunnels enable service providers to segregate customer traffic and extend VLANs across their network IEEE 8021ad Wikipedia Dec 6 2024 QinQ is a technology that expands VLAN space by adding an additional 8021Q tag to 8021Qtagged packets It is widely used on carriers backbone networks to enable packets with double VLAN tags to traverse the network and implement refined user management 什么是QinQ 为什么需要QinQ 华为 QinQ tunneling and VLAN translation allow service providers to create a Layer 2 Ethernet connection between two customer sites Providers can segregate different customers VLAN traffic on a link for example if the customers use overlapping VLAN IDs or bundle different customer VLANs into a single service VLAN Configuring QinQ VLAN Tunnels Cisco QinQ Aruba 8021Q Tunneling QinQ Configuration NetworkLessonscom Configuring QinQ Megaport Documentation QinQ stands for 8021Q in 8021Q QinQ is a flexible easytoimplement Layer 2 VPN technology based on IEEE 8021Q QinQ enables the edge switch on a service provider network to insert an outer VLAN tag in the Ethernet frames from customer networks so that the Ethernet frames travel across the service provider network public network with double VLAN tags Open vSwitch Overview of 8021ad QinQ Support Red Hat Jul 26 2013 QinQ will allow the ISP to assign one VLAN per customer which will be used as the second outer tag for each frame enters the ISP cloud regardless of the initial VLAN inner tag that the customer uses So each frame that belongs to this customer will have two tags when traveling within the ISP cloud Mar 26 2012 Learn how to configure and implement QinQ and L2PT on L2 ports for Layer 2 Tunneling support on Integrated Services Router Generation 2 ISR G2 This feature enables service providers to offer Layer 2 Ethernet services and transparent LAN services over a metropolitan Ethernet infrastructure Learn how to configure 8021Q tunneling aka QinQ for layer 2 VPN between customer sites and service provider network See the topology router and switch commands and verification steps for this technique Dec 6 2024 QinQ是一种扩展VLAN空间的技术通过在8021Q标签报文的基础上再增加一层8021Q的Tag来达到扩展VLAN数量的目的QinQ可以满足企业网和运营商网络的业务精细化管理和VPN技术的需求有基于接口和基于流两种实现方式 Difference between dot1q and QinQ Cisco Learning Network Configuring QinQ Tunneling and VLAN QinQ Tunneling and Configuring QinQ This topic describes ways to connect your onpremises network equipment to a cloud service provider CSP that uses QinQ 8021Q tunneling also known as QinQ or 8021ad is a technique used by OSI Layer astonbed 2 providers for customers 8021ad provides for both an inner and an outer tag whereby the outer sometimes called Stag for service provider can be removed to expose Sep 15 2008 KB35261 EXQFX Understanding QinQ untagged traffic behavior over SVLAN KB36077 EX How to combine CE and PE into a single switch QinQ workaround KB21686 EX QinQ dot1q tunnel to tag traffic from multiple customers which are aggregating on a single interface into separate SVLANs Videos for Qinq QinQ Configuration Network Direction The main advantage for QinQ mixed VLAN mode is that users do not have to dedicate the entire switch as a QinQ access switch For a high density chassis switch such as the 5400zl or 8200zl series customers can use regular ports for normal LAN switching while SVLAN member ports can be configured to access the QinQ provider network see QinQ Hi Rutvij Hope below helps to understand dot1q and QInQ dot1Q 8021Q trunking Protocol 8021Q inserts a 4byte header also called a tag into the original Ethernet frame right after Source Address field instead of encapsulating the Ethernet header QinQ Use Cases rnetworking Reddit Jun 6 2017 QinQ frames look very much like a normal VLAN tagged Ethernet frame The only difference is the presence of a second VLAN tag This means QinQ only adds 4 extra bytes to a frame The above diagram shows a VLAN tagged packet before and after inserting a QinQ tag Enabling QinQ support in OVS is a simple configuration change VXLAN vs QinQ The Network DNA Introduction to QinQ Hewlett Packard Enterprise Support Center May 6 2022 There is a fixed format for QinQ packets The name QinQ comes from the fact that an 80211Q tagged packet is usually enclosed in another 8021Q tag As packets are transmitted over the public network they are forwarded based on their outer VLAN tags Data transmitted through the public network is also taken into account as the inner VLAN tag QinQ is a technique that allows multiple VLAN tags to be inserted into a single Ethernet frame specified by the IEEE 8021ad amendment to the 8021Q standard QinQ is used for metro Ethernet and Layer 2 tunneling and is compatible with 8021Q What Is 8021Qin8021Q QinQ Huawei Wireless Network QinQ is a technology that adds another 8021Q tag to a tagged packet to expand VLAN space Learn about QinQ packet format encapsulation termination and applications in this document IEEE 8021Q Tunneling QinQ and L2PT on L2 Cisco IEEE 8021Q Tunneling QinQ IP Network Labs About QinQ Hewlett Packard Enterprise Support Center QinQ technically doesnt use the normal 8021Q header so if a switch in the SP network expects a 8021q header but cant parse it the frame may be dropped However some QinQ implementations place two 8021q headers after each then it might work I would say it most likely to work if configured indomabet in the SP network
