Hi,


Is it possible to configure L2VPN + Selective QinQ in S6730-H model?


I would like to transport different ranges of CVLAN through different L2VPN from the same interface on PE (shared trunk interface)

The diagram bellow shows the condition on every PE to match traffic to each L2VPN (it seems a VSI is more suitable to this scenario):


l2vpn


My aim is:

* Transport CVLAN 100 to 149 + 200 to 249 + 300 to 349 inside L2VPN A to BNG1

* Transport CVLAN 150 to 199 + 250 to 299 + 350 to 399 inside L2VPN B to CE1

* Be able to configure other VLANs on PE interfaces facing the OLT to switch traffic to other interfaces on the same PE (trunk port)

Hi ptomasi,
The S6730-H supports VPLS and QinQ. You can use VPLS to establish an L2VPN and use QinQ to add double labels to packets.

Hi,

Is there any configuration example about this scenario?


I'm not sure about the configuration on PE interface facing OLT (AC) to include each CVLAN range in the correct L2VPN


Thanks

VPLS and QinQ are two separate protocols. Currently, there is no solution to integrate the two protocols. I will send you a vpls configuration case, hope to help you.

It seems it's possible to achieve that using subinterface + QinQ stacking:


PE1 --> PE3:


#

interface Eth-Trunk4.1001

qinq stacking vid 100 to 149 pe-vid 1001

mpls l2vc 3.3.3.3 1001

#

interface Eth-Trunk5.1002

qinq stacking vid 150 to 199 pe-vid 1002

mpls l2vc 3.3.3.3 1002

#




PE3 --> PE1:


#

interface Eth-Trunk1.1001

qinq stacking vid 100 to 149 pe-vid 1001

mpls l2vc 1.1.1.1 1001

#

interface Eth-Trunk1.1002

qinq stacking vid 150 to 199 pe-vid 1002

mpls l2vc 1.1.1.1 1002
