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.

Hello,
Thanks for the reply. I will look at 802.1ah. Currently our architecture
does not involve physical hardware as we do not have control over it. We
were planning on using the provided private network from the data centre
and separating the traffic of our clients inside this vlan. We just need
to host more than 4094 vlans in such network. Does the openvswitch
support 802.1ah?

Dimitar,
Open vSwitch does not currently support 802.1ad. I have submitted a
patch for 802.1ad and I am in the process of submitting a new version.
However, 802.1ad will not solve the namespace problem. Perhaps you are
thinking of 802.1ah?

Hello,
We are using openvswitch for some time and we are trying to implement
"private vlans" for our customers. Each customer should have vlan(s)
between his/her virtual instances. The problem with 802.1q vlans is that
we are expecting more than 4094 clients per openvswitch instance and the
vlan limit is 4096. We are considering QinQ(802.1ad).
My question is if ovs supports QinQ and how this can be achieved ?
Please propose other approach if this is not a good solution to the
problem.
