I'm not sure if the bridging code is from ET or if it's the standard FreeBSD but it seems to be standard FreeBSD bridging code. root@oahu [8:24pm][/usr/temp/zebra] >> ifconfig bg0 bg0: flags=8843 mtu 1500 inet 216.235.44.1 netmask 0xffffff00 broadcast 216.235.44.255 inet 216.235.45.1 netmask 0xffffff00 broadcast 216.235.45.255 inet 216.235.56.193 netmask 0xffffffe0 broadcast 216.235.56.223 ether 00:00:00:03:00:00 I've asked Dennis at ETinc the question and his response was: if you want to route from one DLCI to the other then you have to put them in separate bridge groups with their own subnet. You are creating isolated segments with the ipmap functionality...the mechanism is designed for end users who get 1 or 2 addresses. You COULD fix the O/S to route back to the same interface, but I dont know how complicated that would be. I dont think there is an easy way to disable split-horizon.
