nice stuff....should be usfull for the certification training
Yeah, i'm looking forward to playing with them more. I've configured the interfaces on the routers to talk to each other and general configuration to start with, hope to do more labs soon.
The two bottom devices are routers, and the top one is a switch. The routers are usually placed at each location and connected to some type of WAN (wide area network) to link all the locations together. Right now, I have them connected with the serial cables (the two cables that cross each other) to simulate a frame relay network, but haven't gotten much farther yet.
Is this a firewall/Router?
These are corporate routers that basically take a WAN connection and "route" the signal through the proper interface. Most routers made by Cisco are designed to accept add-on modules for T1, CSU/DSU, Ethernet connections, etc., but this specific model (2500) doesn't accept those modules. Also there are certain models of these routers that have two Ethernet Interfaces that are called "Integrated Services Routers" (ISR) and you can basically connect a DSL modem to one interface and a switch to another and effectively replace that D-Link router with Cisco.
Basically, the simplest way I can explain a transciever is an adapter that converts an AUI connector (older-style Ethernet that uses a DB-15 connector (looks like a joystick)) into an RJ-45 connector. That's really about all it does. Look at this example:
The long connector in the middle is an AUI connector (older networks used this instead of the usual RJ-45.
Any other questions can be asked and I will try my best to answer them.
