I am trying to network a remote site with a main site through a bridged

gif(4) supports only untagged frames when added to a bridge.
You need to create gif-per-vlan or switch to newer vxlan(4).
I have in the past implemented this using netgraph and vnet
but it was quite a log time ago and I forget many of the details
The vnet jail was so that the gif tunnel effectively left from
"another machine" (it was the same machine with a vnet jail)
The reason was so that net failures were "one hop away" and
therefore not so hard to work around.
In the past, I have set up a similar link by tunneling ip over gif, but
routing turned out to be intricate
what problems do you have with routing over gif? It works just fine for me.
and I figured just bridging the exclave with the main site would save me
routing issues,
And bring in bridging issues that are more severe.
plus I could stick with the existing subnets.
And have extra overhead to pass +14 bytes of headers of MAC addresses per frame.
Single gif+bridge does not support trunks.
