Hi,
By tagging the traffic coming from vport1 and vport2 you've told OVS,
that there will be some other switch in the network, which will know how
to handle tag=10, if you don't have a switch configured to forward
packets having tag=10 they will be just dropped at some point of the
network which drops tagged packets in absence of a different configuration.
Cheers,
Geza
