Part of your CCNA / CCNP training is deciding what community topology to make use of when you're placing collectively your property lab. Some of you are starting with one or two routers or switches, while others are starting with more. A customer just lately despatched me a listing of his Cisco routers and switches that he has out there for a home lab and requested for my assist in developing with the best way to make use of them. There is no such thing as a "right" or "fallacious" reply to this question; once more, part of the learning process is configuring and reconfiguring the physical topology of your lab. Let's take a look at the routers and switches he has accessible, together with the interfaces on every, and give you one attainable CCNA / CCNP home lab setup. The equipment list: Two 3620 routers. Each has 1 serial port and a pair of ethernet ports. One 3640 router. This has two ethernet cards, every with ports, and AUI ports. Three 2503s, my private favorite for house labs! These have 1 AUI port, 2 serial interfaces, and one BRI interface apiece. One 2524 router. This has one serial port, 1 ethernet port, and one BRI interface. One 4500 router. This has eight BRI ports, 2 ethernet ports, and extra importantly, 4 serial ports. He also has a 5200 entry server, an ISDN simulator, one 2924 swap, and one 1924 switch. Now, if you don't have this a lot gear to work with, don't panic! Most CCNA / CCNP candidates do not; this is extra of an train in looking at what you do have and utilizing it to the utmost. As I've mentioned in many of my CCNA / CCNP house lab articles, an access server is a good thing to have. All he wants is an octal cable to attach his AS to the other gadgets we select to use, and he is all set. (In the event you want an access server pattern configuration, there's one on my web site in the Residence Lab section.) A body relay swap can also be great to have, and the 4500 will make a terrific FR switch. Having a frame relay cloud in your CCNA / CCNP house lab is a good way to get expertise configuring and troubleshooting frame relay, an essential ability for CCNA success. I would put both of the 3620s on the frame relay cloud by way of the Serial interface, as well as of the 2503s. That offers you four routers that will likely be utilizing frame relay to communicate, and that is the most we will have because the 4500 has 4 serial ports. The 4500 will have to be configured as a body relay swap and connected to the opposite routers through a DTE/DCE cable. (Once more, in the event you want a frame relay swap configuration, the one I use in my pods is on the web site in the same place as the access server configuration.) The 2 2503s which are on the body relay cloud also needs to be linked through their BRI interfaces. The house lab additionally includes an ISDN simulator, which is important to permit routers to speak through their BRI interfaces. Just get a couple of straight-by cables to attach these two routers to the ISDN simulator and that segment is ready to go. (Bear in mind that you would be able to't connect Cisco routers instantly by way of their BRI interfaces.) All the routers in this lab have no less than one ethernet or AUI port, so we will join them all to either one of many switches. The switches ought to be related by way of not less than crossover cables to allow observe with trunking, root bridge election, and VLANs. Having two switches really does add fairly a bit to a CCNA / CCNP residence lab's capabilities. You'll be able to experiment with completely different subnets and vlans with as well. Do not be afraid to dive in - that is what a house lab is all about! So now we've got four routers linked via frame relay, two via ISDN, and the others through ethernet segments. Two of the routers that aren't utilizing their serial interfaces must be related immediately through their serial ports. For this, you may just want another DTE/DCE cable. Knowing how to convey up the road between two directly connected serial ports is an important CCNA ability, and so is troubleshooting it. You must be capable to bring such a connection up along with your eyes closed, and as soon as you work with your personal CCNA / CCNP house lab, you can! Additionally, remember so as to add a loopback interface to every one among your routers. I like to use 1.1.1.1 for R1, 2.2.2.2 for R2, and so on. Promoting loopbacks is another nice approach to get follow with RIP, OSPF, EIGRP, IGRP, and static routing. We have taken a pile of routers and switches and turned them right into an implausible CCNA / CCNP home lab. Whether or not you're working with Cisco gadgets or ten, developing with your own dwelling lab topology is a good learning experience and the start of growing
