in reference to the following specification about the creation of VLAN
trunking network for NFV
I would like to better understand how the tagged traffic will be
realized. In order to explain myself, I report the following use case:
A VNF is deployed in one VM, which has a trunk port carrying traffic for
two VLANs over a single link able to transport more than one VLAN
through a single integration-bridge (br-int) port. So, How does br-int
manage the VLAN-ID? In other words, what are the action performed by the
br-int when a VM forwards traffic to another host?
Does it put an additional tag or replace the existing one keeping the
match with a table or something like that?
Thank you very much.
