In my impression,most switches can not afford to large number of 802.1q vlan trunk. hundreds of tunk vlan will cause the machine poor performance or crash. I suffer it with some intel's switches before. I heard cisco and other vendor suggest not to use too many vlan trunk in their machine. is it t

Before going down this road, I tend to wonder what drives people this direction. Exactly what is it about poorly scaling, flat networks that turn people on? Last I checked, IP did a pretty decent job of providing a robust means of interconnection between remote sites. To me, its LANE all ov

I cannot see any problem using vlan from your access layer up to the aggregation point, as long as the PE has enough capacity to hold the routes. If necessary, you can always use several PEs in one location to spread out your aggregation, you may want to use some lower end routers/switches, kind o

we are handling a case of a MAN project now. We plan to use mpls-l2 vpn to connect the business subscribers.That means we have to place some mpls-enabled machines on the access nodes(expensive...). Another choice is using vlan.And the users' vlan are trunked to the aggressive nodes.I think it's no
