What's the purpose of trunk network?
Can you please add a use case that trunk network can't be
optimized away?
In some use cases the trunk network will trunk all VLANS from a VM, so
they can for example be 'tunneled' to another VM or externally. In the
use case where a VM wants to connect to multiple Neutron networks, the
trunk network is a logical connection between the VM trunk port and
the L2-gateways. From my point of view it looks a little strange for
this use case, but I think this is what we said during our meeting in
Hong Kong (Unless I misunderstood something...).
I added use case where two VMs are connected through a trunk network.
This can not be optimized away. The network would have to be able to
trunk all VLANs between the VMs.
I see the case where admin user wants to have more than one L2 gateways
to talk to the same VM trunk port. Also, these L2 gateways may connected
to the untagged networks that belongs different tenants. The trunk
network should belong to a single tenant though.
