I know from experience that an element of the excitement and anxiety of placing together your personal CCNA / CCNP house lab is deciding the things to purchase! While you can also make a workable dwelling lab out of virtually any mixture of Cisco routers and switches, some routers are higher suited for residence lab perform than others as a result of they'll fill multiple roles.
My personal favourite is the Cisco 2520. This router comprises four serial interfaces, making it an excellent body relay switch. Don't forget that simply since you're utilizing a router as a body swap, you may still charge its routing capabilities. One setup I use is to generate charge of three of the 4 serial interfaces used for body switching and the fourth interface as some extent-to-point network with one other router. All you want is a few DTE/DCE cables and also you're all set.
The 2520 additionally comes through one ethernet interface and an ISDN interface, so that offers you even more options. Even for those who're not planning to run ISDN in your home lab proper now, it's possible you'll choose to take action in the future - and through a 2520, you've already obtained the right router toward do so. Understand that if you're going to run ISDN in your house lab, you'll need an ISDN machine equivalent to an ISDN simulator in your lab. (ISDN simulators are physical devices and are plentiful on ebay - they're no relation to "router simulators".)
Once more, I wish to reiterate that you may serve any Cisco router into a CCNA / CCNP residence lab - there isn't any "right" or "incorrect" mixture of equipment. But as through anything else, some combos are higher than others, so take into account including some 2520s toward your property lab! This router offers you an excellent mixture of interfaces and capabilities, as well as the largely important issue of all - actual arms-on experience throughout your CCNA and CCNP exam preparation!
