QinQ Configuration Example Assume Switch A customer port is gei_3/1 and uplink port is gei_3/24; Switch B customer port is gei_7/1, uplink port is gei_7/24. SPVLAN 10 Customer port SPVLAN 10 Uplink port User's Network 1 CVLAN1~100 Switch A ISP Networks User's Network 2 CVLAN1~100 PE SPVLAN 10 uplink port Switch B Double tag service Add the designated outer VLAN tag (ovlan) according to the designated inner VLAN (in-vlan). Data uplink：Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan. Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port. [related command]ZXR10(config)#vlan qinq session 1 customer gei_3/1 uplink gei_2/1 in-vlan 63-1023 ovlan 999 Double tag ＋ designated priority According to the designated inner vlan, add the designated outer vlan tag, and add the designated priority; schedule and forward the data traffic according to the designated priority. Data uplink: Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan, and add the designated 802.1P priority. Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port. [related command]ZXR10(config)#vlan qinq sessin 2 customer fei_5/1 uplink gei_1/1 in-vlan 64-256 ovlan 997 priority 5 Double tag + mapping priority According to the designated inner VLAN, add the designated outer VLAN tag, and map the inner VLAN priority to the outer VLAN tag priority. If the inner tag priority is not considered, it does not need to map. Data uplink: Classify data traffic entering from customer port and add the outer tag ovlan to packets with in-vlan, and map the inner VLAN priority of each packet to the outer VLAN.Data downlink: When packets with double tag flow to the uplink port, forward them according to L2 forwarding principle; strip the outer tag from them when the packets are forwarded on the customer port. [related command]ZXR10(config)#vlan qinq session 3 customer gei_2/1 uplink gei_1/1in-vlan 4-128 ovlan 2000 priority mapping VLAN transparent transmission service For the designated VLAN transparent transmission, do not add the outer tag. Data uplink: Classify data traffic entering from customer port and add the helper_vlan outer tag to packets with in-vlan, with the aim to aggregate multiple transparent transmission vlans, encapsulate channel with helper_vlan, strip helper_vlan on the outgoing interface and transparently transmit the packets. Data downlink: Transparently transmit VLAN data traffic to the uplink port, and according to L2 forwarding principle, forward the traffic from the customer port in original shape. [related command]ZXR10(config)#vlan qinq session 4 customer fei_2/1 uplink gei_2/2n-vlan 50-56 untag helper-vlan 1 Untag packet service This type of service is rare. For packets without tag entering the customer port, add the corresponding VLAN tag on the outgoing interface. Data uplink: Classify data traffic entering from customer port, and for untagged packets, if they are configured with the egress tag, add the designated VLAN tag instead of adding the outer tag according to PVID of the port. Data downlink: the downlink data packets are forwarded normally. [related command]ZXR10(config)#vlan qinq session 5 customer fei_1/2 uplink gei_1/12 untag ovlan 1000 PE SPVLAN 10 Customer port SPVLAN: Service Provider VLAN CVLAN: Customer VLAN

Configure SVLAN rule for packet without tag ZXR10(config)# vlan qinq session-no <session-id> customer-port <port-id> uplink-port <port-id>{untag ovlan <vlan-id>[undirect]} Display SVLAN configuration information ZXR10(config)# show vlan qinq [session <session-id>] 8

SVLAN Configuration Example BRAS T600(vpls) 8905 2826E uplink:gei_1/3 uplink:gei_1/4 customer:gei_1/1 customer:gei_1/2 100-500 600-1024 3000 1100:untag 997:100-500(gei_1/1) 998:100-500(gei_1/2)

SVLAN Configuration Example –Requirements For datagram of VLAN 100-500 from 8905 gei_1/1 (assume the frames of this VLAN range to be PPPOE dial-in user), add outer tag vlan997 on 8905 and uplink to BRAS via gei_1/4. For datagram of VLAN 100-500 from 8905 gei_1/2 (assume the frames of this VLAN range to be PPPOE dial-in user), add outer tag vlan998 on 8905 and uplink to BRAS via gei_1/4. For datagram of VLAN 600-1024 from 8905 gei_1/1-2 (assume the frames of this VLAN range to be private network user), transparently transmit these VLANs via 8905 and uplink to T600 via gei_1/3. For the untagged frames received on 8905 gei_1/1-2, add a tag 1100 on 8905 and uplink to T600 via gei_1/3; Configure vlan3000 as management VLAN, used to manage 8905 and 2826E via T600, management VLAN should contain no outer tags.
