You have some further considerations too: What will your fabulous net-
work design require regarding port density and interface speeds? As you may
have guessed, when you get into the higher-end models, you'll find more
ports and faster speeds. For example, the new 12000 series model is Cisco's
first Gigabit Switch Router (GSR), and its functions, features, and capabili-
ties are beyond dazzling!
It's weird, but you can tell how much a product is going to cost by looking
at its model number. A stripped-down 12000 series GSR with no cards or
power supplies starts at about $12,000, but know that the price can end up
at well over $100,000 for a loaded system.
You also need to think about WAN support when buying a router. You
can get anything you want in a Cisco router, but you must first be familiar
with the service provided for your area.
Figure 1.21 shows some of the router products Cisco sells.
