[ovs-discuss] Questions on PVLAN behavior with Cisco switch

Yes it does. The mac learning will still work.

I was thinking about the following sequence with multiple
virtualizers connected to Cisco switches via 802.1q trunks.

1) A vm in <40,41> send a packet which cross multiple trunks (One between
the virtualizer and the Cisco and another between two Cisco).
2) It finally reach the router which is behind a promiscious port belonging
to pvlan 40.
3) The router send it's reply.

As multiple virtualizer are trunked to the same Cisco switch will the reply
packet be transferred only once to the right virtualizer ?

Best regards

Benoît
