It depends on what you're trying to do. If you want real switches and virtual routers then you need one NIC per router Ethernet interface. The problem I ran into was that I needed more NICs than I had slots in my Dynamips server. I have two 4 port Ethernet cards plus the two built in cards and I still didn't have enough. I was looking at maybe buying some USB NICs, but I never got that far with it.
There's a pretty good tutorial at the dynagen site.
