I want to build a filtering bridge between two 802.1Q VLAN-Trunk interfaces and in the meantime I assume that I make some mistakes configuring the bridge... Actually I configured the bridge (for one VLAN only as an example) "bge0:1,bge1:1,vlan0:2,vlan1:2", where 'vlan0' has the parent interface 'bge0' and the same for index 1. But I'm uncertain, if this is correct. First, the man-page says, "By putting both physical and logical (vlan(4)) interfaces in the same cluster, a FreeBSD box can also implement what in commercial terms is called a ``trunk'' interface." I understand this as "bge0:1,bge1:1,vlan0:1,vlan1:1,...." Does this keep the several VLANs isolated from each other? Have the parent interfaces to be in there? Why? Or is my original configuration correct to put each VLANs vlan(4) interfaces in their own cluster? Again, have the parent interfaces to have their own cluster? Have they to appear anyway? In an example in bridge(4) I read they must not appear to avoid loops... I must admit, I'm a bit confused :-} Can anybody explain this more clearly to me?
