No error messages? I think recently bridge started allowing IPs on bridge only, not on member interfaces... (there is some sysctl for temporary workaround, not recommended in general - it will be gome some day)

It works on member interfaces for the moment with the default sysctl values. That will/may change for 16. So, that's not the problem here. And to be frank, I don't understand what it is, to put it mildly.

Move your IP to the bridge and just attach the physical interface to the bridge.

dear all :
use bastille create vnet jail222 and touch vm-mylan bridge . use bhyve create a vm333 and touch tap to vm-mylan bridge ..
assign jail222 IP: 192.168.1.222/24 , assign vm333 IP : 192.168.1.333/24 .. vm-mylan bridge don't assign any IP .
add re0 to vm-mylan bridge ... assign re0 IP 192.168.1.1/24 ...
now , we don't change any sysctl configure , all was default ...
vm333 can ping jail 222,
jail222 can ping vm333,
jail222 can ping re0 ,
vm333 can ping re0 ,

but when you power off vm333 . jail222 can not ping re0 ...
i don't know what happened....
