Involvement of your CCNA / CCNP upbringing is deciding what network topology to speak when you’re putting together your people’s home lab. Some of you are starting with one or two routers or switches, while others are starting with more. A guy recently sent me a rota of his Cisco routers and switches that he has within reach for a habitation lab and asked in compensation my steal in coming up with the best disposition to use them.

There is no “right” or “wrong” conform to to this theme; again, role of the learning development is configuring and reconfiguring the diplomate topology of your lab. Arrange for’s look at the routers and switches he has within reach, including the interfaces on each, and take up with united possible CCNA / CCNP haunt lab setup.

The accoutrements list:

Two 3620 routers. Each has 1 serial refuge and 2 ethernet ports.

At one 3640 router. This has two ethernet cards, each with two ports, and two AUI ports.

Three 2503s, my special favorite for home labs! These from 1 AUI anchorage, 2 serial interfaces, and undivided BRI interface apiece.

Identical 2524 router. This has one serial port, 1 ethernet mooring, and unified BRI interface.

Limerick 4500 router. This has eight BRI ports, 2 ethernet ports, and more importantly, four serial ports.

He also has a 5200 access server, an ISDN simulator, lone 2924 change, and joke 1924 switch.

Contemporarily, if you don’t have this much appurtenances to master-work with, don’t dismay! Most CCNA / CCNP candidates don’t; this is more of an wield in looking at what you do possess and using it to the utmost.

As I’ve mentioned in uncountable of my CCNA / CCNP to the heart lab articles, an access server is a great obsession to have. All he needs is an octal line to put together his AS to the other devices we decide to from, and he’s all set. (If you need an access server test configuration, there is harmonious on my website in the Home Lab section.)

A elevate relay beat is also huge to from, and the 4500 determination force a enormous FR switch. Having a frame relay cloud in your CCNA / CCNP bailiwick lab is a superb character to punch common sense configuring and troubleshooting frame relay, an important knack benefit of CCNA success.

I would put both of the 3620s on the frame relay cloud via the Serial interface, as well as two of the 2503s. That gives you four routers that liking be using mould relay to communicate, and that’s the most we can take since the 4500 has four serial ports. The 4500 thinks fitting lack to be configured as a system relay direct and connected to the other routers via a DTE/DCE cable. (Again, if you desideratum a edging relay switch configuration, the rhyme I use in my pods is on the website in the in spite of place as the access server configuration.)

The two 2503s that are on the support relay cloud should also be connected via their BRI interfaces. The tellingly lab also includes an ISDN simulator, which is necessary to cede to routers to down via their BRI interfaces. Impartial get a two of straight-through cables to connect those two routers to the ISDN simulator and that split is ready to go. (Remember that you can’t affix Cisco routers without delay via their BRI interfaces.)

All of the routers in this lab arrange at least anyone ethernet or AUI seaport, so we can affiliate them all to either the same of the switches. The switches should be connected via at least two crossover cables to allow custom with trunking, destroy unite election, and VLANs. Having two switches honestly does count up actually a speck to a CCNA / CCNP hospice lab’s capabilities. You can procedure with diverse subnets and vlans with as well. Don’t be timid to plunge in - that’s what a rest-home lab is all surrounding!

So in the present climate we’ve got four routers connected via frame relay, two via ISDN, and the others via ethernet segments. Two of the routers that are not using their serial interfaces should be connected momentarily via their serial ports. During this, you’ll just need another DTE/DCE cable. Sly how to convey up the policy between two promptly connected serial ports is an important CCNA facility, and so is troubleshooting it. You should be superior to bring such a influence up with your eyes closed, and once you post with your own CCNA / CCNP home lab, you’ll be able to!

Also, don’t omit to enlarge a loopback interface to each sole of your routers. I like to utilize 1.1.1.1 for R1, 2.2.2.2 instead of R2, and so on. Advertising loopbacks is another great trail to accumulate modus operandi with RIP, OSPF, EIGRP, IGRP, and immovable routing.

We’ve taken a wad abundance of routers and switches and turned them into a bizarre CCNA / CCNP accommodations lab. Whether you’re working with two Cisco devices or ten, coming up with your own abode lab topology is a terrific learning experience and the beginning of developing your analytical and troubleshooting skills.
