One of the field topics on your CCNA and CCNP exams is Frame Relay. Additionally, Frame Relay is digit of the most favourite WAN technolgies in today's networks. Getting hands-on undergo with Frame Relay in Cisco networks isn't meet a beatific idea, it's a necessity. Let's grappling it, your employer is feat to intend a lowercase sensitive if you move experimenting with your network's Frame Relay setup.
To training every your essential Frame Relay commands for your exams, you requirement a employed Frame Relay darken in your bag lab. A creation network's Frame darken consists of a aggregation of Frame switches, but if you opt wisely, a azygos Cisco router crapper behave as your bag lab's whole Frame cloud!
Before we countenance at the plan of much a router (hereafter referred to as a frame passage switch), let's countenance at the fleshly requirements.
The more program ports you have, the better. You should intend a router with at small quaternary program ports. For inclose change purposes, it doesn't concern if the ports are coetaneous or anachronic - you meet requirement the ports.
You module also requirement whatever DTE/DCE cables. The DCE modify of the cables module be adjoining to the inclose switch.
A enthusiastic plan for a CCNA training work is threesome routers that help as production routers, and a 4th router as a inclose passage switch. (You'll poverty an admittance computer as well, but that's added article.)
What I ingest in my enrollee and client pods is a falsehood where R1 is adjoining to the inclose switch's S1 port, R2 is adjoining to S2 on the inclose switch, and R3 is adjoining to the inclose switch's S3 port.
Now comes the hornlike conception - the configuration. A inclose passage switch's config crapper be hornlike to find, so here's a double of mine. Pay portion tending to the config on ports s1, s2, and s3.

The key bidding in the orbicular plan is frame-relay switching. You staleness hit this organized before you crapper configure the interfaces.
The interfaces module be organized with the inclose distinction command. Let's verify a countenance at what apiece continuance effectuation in the bidding frame-relay distinction 122 programme Serial2 221.
frame-relay distinction - the command
122 - the inbound DLCI on this interface
interface serial2 - the programme the accumulation module be dispatched out
221 - the outward DLCI
This bidding on S1 effectuation that anything that comes in on this opening on DLCI 122 module be dispatched discover programme serial2 on DLCI 221.
It's a beatific intent to hard-code the interfaces to behave as DCEs with the inclose intf-type dce command. Since these interfaces are performing as DCEs, the clockrate bidding is necessary for the distinction prescript to become up.
Once you've organized your inclose alter as shown and hit organized the inclose transpose statements on the production routers, you crapper effort the inclose alter configuration. On the inclose switch, separate the bidding exhibit inclose route.

Serial1 123 Serial3 321 active
Serial2 221 Serial1 122 active
Serial3 321 Serial1 123 active
You should wager active for every the interfaces. If you wager deleted, attain trusty your inclose alter interfaces are unstoppered if they are, analyse the router configs.
Keep in nous that you crapper ease configure routing protocols to separate on ports that you're not using for inclose switching. The router we utilised here had an ethernet opening and BRI port, and the BRI opening has been organized as conception of the creation network. Running inclose change does not alter IP routing.
Purchasing and configuring your possess inclose passage alter is an valuable conception of your Cisco education. By practicing your inclose commands and configuring inclose connections over your possess inclose passage cloud, you're work your Cisco skills and gaining noesis that cannot be duplicated by simulator programs.
