In the Exam Certification Guide, Phase 2 Integrated Services is described as many services residing in one device or many devices providing one service.
The many-on-one example discusses the Cisco ISR which I have no problem with, but then it says the opposite is taking one resource and making it "look like many". This contradicts the initial description in my mind. It talks about one router running multiple virtual routers, which sounds more like a many-on-one example. A more appropriate example would seem to be a server cluster where multiple servers appear as one server.
Can someone please clear this up for me? It just seems like virtual routers is another example of many-on-one, and not a one-on-many example.
