Thinking about it more, isn't it carp over trunk over vlan over
nic? I'm gonna give it a shot here in the next day or so.
No. The OpenBSD trunk device is for link aggregation and failover,
both properties of the physical layer. The OpenBSD vlan device
provides access to VLAN segments (802.1Q), properties of the data-
link and network layers.
Again, make sure you're not confusing vendor terminologies here. An
OpenBSD trunk is what many vendors refer to as teaming or bonding
(some do refer to it as trunking). However, many(?) vendors refer to
a trunk as a port carrying multiple tagged VLANs.
