I'm quite willing to believe that FreeBSD's loop detection works great for the situation where bridged interfaces are put on the same subnet. -- -Chuck #if defined(SENSE_OF_HUMOR) Spanning tree protocol, link aggregation (or "port trunking", etc), and other layer-2 stuff found in managed switches still have their uses. For some odd reason, a Tom Lehrer song about Werner von Braun is coming to mind-- "FreeBSD forwards the packets, who cares whether they loop around." :-) #endif
