Cisco CCNA / CCNP Tutorial: To the quick Lab Convocation Example in any event Con
Involvement of your CCNA / CCNP edification is deciding what network topology to speak when you’re putting together your home lab. Some of you are starting with unified or two routers or switches, while others are starting with more. A guy recently sent me a book of his Cisco routers and switches that he has available for a at ease lab and asked in compensation my cure in coming up with the best feeling to drink them.
There is no “proper” or “awry” plea to this question; again, fragment of the information course of action is configuring and reconfiguring the diplomate topology of your lab. Farm out’s look at the routers and switches he has readily obtainable, including the interfaces on each, and take up with united possible CCNA / CCNP home lab setup.
The accoutrements list:
Two 3620 routers. Each has 1 serial seaport and 2 ethernet ports.
A certain 3640 router. This has two ethernet cards, each with two ports, and two AUI ports.
Three 2503s, my dear favorite in search diggings labs! These compel ought to 1 AUI anchorage, 2 serial interfaces, and single BRI interface apiece.
One 2524 router. This has one serial mooring, 1 ethernet mooring, and bromide BRI interface.
A woman 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, united 2924 alteration, and only 1924 switch.
Now, if you don’t accept this much appurtenances to achievement with, don’t dismay! Most CCNA / CCNP candidates don’t; this is more of an exercise in looking at what you do bear and using it to the utmost.
As I’ve mentioned in sundry of my CCNA / CCNP home lab articles, an access server is a immense thing to have. All he needs is an octal mooring to attach his AS to the other devices we choose to object, and he’s all set. (If you have need of an access server test configuration, there is one on my website in the Bailiwick Lab section.)
A arrangement relay lash is also out-and-out to from, and the 4500 will make a skilful FR switch. Having a construct relay cloud in your CCNA / CCNP home lab is a great character to punch face configuring and troubleshooting frame relay, an important expertise instead of CCNA success.
I would put both of the 3620s on the support relay cloud via the Serial interface, as evidently as two of the 2503s. That gives you four routers that see fit be using mould relay to offer, and that’s the most we can have since the 4500 has four serial ports. The 4500 devise desideratum to be configured as a system relay exchange and connected to the other routers via a DTE/DCE cable. (Again, if you desideratum a scaffolding relay beat configuration, the anybody I put in my pods is on the website in the verbatim at the same time hit pay dirt as the access server configuration.)
The two 2503s that are on the frame relay cloud should also be connected via their BRI interfaces. The people’s home lab also includes an ISDN simulator, which is life-or-death to concede routers to correspond with via their BRI interfaces. Principled get a several of straight-through cables to sew those two routers to the ISDN simulator and that component is ready to go. (About that you can’t fasten Cisco routers straight away via their BRI interfaces.)
All of the routers in this lab have at least unified ethernet or AUI anchorage, so we can buckle them all to either the same of the switches. The switches should be connected via at least two crossover cables to cede to technique with trunking, forefathers bridge referendum, and VLANs. Having two switches actually does add somewhat a minute to a CCNA / CCNP conversant with lab’s capabilities. You can investigate with diverse subnets and vlans with as well. Don’t be timid to nosedive in - that’s what a profoundly lab is all about!
So conditions we’ve got four routers connected via edging relay, two via ISDN, and the others via ethernet segments. Two of the routers that are not using their serial interfaces should be connected directly via their serial ports. For the benefit of this, you’ll by a hair’s breadth fundamental another DTE/DCE cable. Crafty how to carry up the activity between two unswervingly connected serial ports is an foremost CCNA facility, and so is troubleshooting it. You should be skilled to fetch such a connection up with your eyes closed, and once you undertaking with your own CCNA / CCNP composed lab, you’ll be able to!
Also, don’t forget to add a loopback interface to each one of your routers. I like to use 1.1.1.1 in behalf of R1, 2.2.2.2 for R2, and so on. Advertising loopbacks is another spacious modus operandi to accumulate practice with DECEIVE, OSPF, EIGRP, IGRP, and problems routing.
We’ve entranced a heap of routers and switches and turned them into a nightmarish CCNA / CCNP accommodation lab. Whether you’re working with two Cisco devices or ten, coming up with your own hospice lab topology is a immense knowledge event and the origin of developing your analytical and troubleshooting skills.
