Basically I'd like to keep two filtering bridges on the network at the same time, one primary and one backup. However, since freebsd bridging doesn't support STP, I can't do that without creating a loop. Is there something (like the vrrp implementation but for bridges) that I can use? Theoretically I can interconnect the two bridges over a serial port and write some sort of heartbeat application, but I'd rather have a solution that has already been tested. Also, my simplistic solution would cause existing connections to be disconnected during the failover.
