They are created and destroyed dynamically when bhyve clients are run. --- Yes, but at the current state of the network subsystem and if_bridge(4) in particular the operator is expected to create all interfaces and bridges in advance and the dynamically attach VMs or jails to these. Dynamically creating bridge interfaces was never supported if either - the bridge member interface providing the connectivity to the outside wor= ld had an IP address configured - the bridge member interface had any VLANs configured with it as the parent I see that Lexi is investing a lot of work into reworking this part of the stack. And I am curious where this will lead. Great work! I am merely stating that in FreeBSD 13 and 14 the known and documented state is: - a bridge member must not have an IP address - a bridge member must not be a parent to any VLAN interfaces So technically speaking there is no bug here. Just a misconfiguration. Kind regards, Patrick --=20 You are receiving this mail because: You are the assignee for the bug.=
