[ovs-discuss] QinQ support

[Thomas F Herbert]

Dimitar,

802.1ad will separate client traffic from each other and from provider 
traffic. Each level of VLAN tag will is 12 bits. So you could have 4096 
provider VLANS and then within each of those provider VLANS you could 
have 4094 "customer" or in your case client VLANs.

You can try our patch for 802.1ad but you will have to build OVS from 
source.

As is the case with 802.1ad, openflow spec supports 802.1ah (PBB) but 
OVS doesn't support it as yet.

There have been several contributions toward this goal. We at EntryPoint 
hope to work on this as well after 802.1ad.
