Technically all routers are switches (or groups of switches in the case of GSR's and M series, etc). Unless you are doing process switching (not recommended) all the routing function really does is generate and cache a series of forwarding destinations for the switching ASIC's. Once this is done all the packets are switched the same way they are in layer 2 devices. There are some functions that come along with L3 intelligence such as ACL's,/FW filters and QOS but even here the actual work is done by the switching ASIC's, but this is all semantics anyway.

We haven't seriously looked at Foundry MLX and XMR, so I can't comment on those. We *do* know quite a bit about Cisco 6500/7600 and how well turning a switch into a router has worked for them. Knowing this we are very glad that the Juniper MX series "inheritance" is from the router side...
