The easy config -- switch = router gives the 24 collision domains. The easy config, give one interface one network address, route somehow (static -- OSPF), and off you go. What if, say, you want two (or three or ten) switch/router ports as a single virtual bridge/hub/switch? The not-unusual collapse of a server or two to the MDF for a specific VLAN/subnet is such a 'typical'. How might one cleverly use the 2948G-L3 (and relatives) BVI/IRB system to route selected ports for multiple VLANs (e.g., in G-L3'ese "BVI and bridge groups with Integrated Routing and Bridging")? These are not just 'how-to's', but understanding just how the L3 fits into 'The Cisco Way' is indeed an enjoyable journey. Welll, mostly enjoyable.

You are correct in the part of 24 separate collision domains which also allows you to put the 24 ports in Full Duplex mode. The part about 24 broadcast domains would only hold true if each port were in a different VLAN no 2 ports in the same VLAN. I.E. a port is an isolated collision domain and a VLAN is an Broadcast domain. Scott NetEng wrote: > I understand the layer3 switching concept, but what happens to broadcast > based services?
