Cisco Home Lab Tutorial: Purchasing And Creating a Frame Relay Change
One of several major matters on the CCNA and CCNP exams is Body Relay. In addition, Frame Relay is among the most well-liked WAN technolgies in nowadays’s networks. Obtaining fingers-on working experience with Body Relay in Cisco networks isn’t just a good suggestion, it’s a requirement. Enable’s confront it, your employer is going to get a bit Sensitive if you start experimenting with all your network’s Body Relay setup.
To exercise all of your important Frame Relay instructions for your personal exams, You will need a Performing Body Relay cloud in your home lab. A creation network’s Body cloud consists of loads of Body switches, however, if you decide on sensibly, only one Cisco router can work as your own home lab’s complete Frame cloud!
Prior to we look at the configuration of such a router (hereafter generally known as a “body relay swap”), Permit’s look at the Actual physical demands.
The greater serial ports you may have, the better. You should obtain a router with a minimum of four serial ports. For body switching reasons, it doesn’t make a difference In the event the ports are synchronous or asynchronous – you simply want the ports.
You will also will need some DTE/DCE cables. The DCE conclude from the cables might be connected to the frame swap.
An incredible configuration for your CCNA observe lab is 3 routers that function “output” routers, in addition to a 4th router to be a body relay change. (You’ll want an access server too, but that’s An additional write-up.)
What I use in my pupil and purchaser pods is really a setup where by R1 is connected to the frame swap’s S1 port, R2 is connected to S2 over the body swap, and R3 is connected to the frame change’s S3 port.
Now comes the tricky element – the configuration. A body relay swap’s config is usually hard to find, so below’s a duplicate of mine. Pay out particular notice on the config on ports s1, s2, and s3.

The true secret command in the global configuration is frame-relay switching. You should have this configured before you decide to can configure the interfaces.
The interfaces will likely be configured Using the frame route command. Let’s take a look at what each benefit signifies within the command frame-relay route 122 interface Serial2 221.
frame-relay route – the command
122 – the incoming DLCI on this interface
interface serial2 – the interface the information is going to be despatched out
221 – the outgoing DLCI
This command on S1 implies that anything at all that is available in on this port on DLCI 122 is going to be sent out interface serial2 on DLCI 221.
It’s a good idea to tough-code the interfaces to work as DCEs with the frame intf-kind dce command. Considering the fact that these interfaces are performing as DCEs, the clockrate command is necessary for the road protocol to come up.
Once you’ve configured your body swap as proven and also have configured the body map statements on the “creation” routers, you can take a look at the frame switch configuration. On the frame swap, operate the command show body route .

It is best to see “Lively” for all of the interfaces. Informatique-Paris If you see “deleted”, be certain your body switch interfaces are open When they are, Test the router configs.
Remember that you can however configure routing protocols to run on ports that you simply’re not making use of for frame switching. The router we used right here experienced an ethernet port and BRI port, plus the BRI port has become configured as Component of the output community. Working frame switching will not disable IP routing.
Buying and configuring your personal body relay switch is a useful portion of one's Cisco education and learning. By working towards your frame commands and configuring frame connections around your own private frame relay cloud, you’re sprucing your Cisco techniques and attaining know-how that cannot be duplicated by simulator plans.
