I have two Soekris NET5501 boards that I wish to deploy FreeBSD = (NanoBSD) on and I'm trying to make sure I can setup everything before I = move ahead. Here's my network design: = http://imageshack.us/photo/my-images/191/networkc.png/ I have an uplink to my ISP on a 2 IP /30 network (1.1.1.0/30 in the = diagram) along with a public routable /28 network (10.0.0.0/28 in the = diagram). I need to bridge the /28 network into the core on a VLAN so I = can easily add hosts deep in the network with IPs from the /28 network. = The trouble I'm having is setting up RSTP on the lagg0.4 interfaces. = =46rom what I've read you have to use MSTP for VLAN interfaces but I = can't find anything about FreeBSD implementing MSTP. RSTP on vr0 is not = a problem but I get "invalid argument" with ifconfig bridge0 stp lagg0.4 = since it's a VLAN interface. Am I overcomplicating this or am I just out of luck on this one? Thanks in advance, Matthew=
