Yes, that was the first place I looked, along with various web pages on
bridging. It seems that bridging only two interfaces is what is covered.

The middle one, I'm not getting as far as pinging the net5501 bridge
interface.
I've bridged vr0 - vr3 and they show up in the bridge. I've assigned an
IP number to vr0 and serve DHCP to that ip range. If I connect to vr0,
I can get an address via DHCP. If I connect to the other ports, then I
cannot. If I understand correctly, connections from vr1 - vr3 will be
bridged to vr0 and will get DHCP from vr0 via the bridge, but that is
not happening.
