Routers historically broker computer communications between a local area network and other networks. Because there were many models of the Cisco 2500 Series router produced with different physical characteristics, some details will vary, but the configuration process does not.
Difficulty: Moderately Challenging
Instructions
Things You'll Need:

* Cisco 2500 Series router
* Computer or terminal for programming the router
* Rollover cable terminated for an RJ-45 connector
* AUI Ethernet and/or Tokenring connections if desired
* Modems if desired

Planning
1.
Step 1

Examine the system. There were several models of 2500 manufactured, but they typically involved Ethernet and TokenRing interfaces for the Local Area Network (LAN), and serial ports for modem connections to one or more Wide Area Networks (WANs). You will note that though there are RJ-45 jacks in the back of the unit, they are not for 10BaseT Ethernet. The only Ethernet connection is the AUI connection, thicknet. If you are connecting this unit to a different Ethernet topology, you may need an adapter. Note that this AUI interface is 10 megabits per second.
2.
Step 2

Consider the console port. This router was designed to be configured locally using a hard-wired terminal, or through a modem connection used to dial directly into the unit. To use this console port, either find a computer with a classic DB-9 or DB-25 to RJ-45 serial port adapter or find a dumb terminal with such connective gear.
3.
Step 3

Use the right cable. Ensure the cable between the PC and the console is a "rollover" cable. Such cables have opposite wiring patterns in the terminators. If you hold the terminators next to one another, the pattern of wires in the terminators will be a mirror image of one another. If orange with a stripe is left-most on in one terminator, then it should be right-most in the other.
4.
Step 4

Match terminal settings. Your terminal, or the terminal emulation software you're using, if you're configuring the system from a computer, must have the same communications settings as the router, or the console port will not work. The console port requires 9600 baud, 8 data bits, no parity, and 2 stop bits.
Initial Setup
5.
Step 1

Boot the router. The firmware will automatically try to load its operating system from Flash memory within the router. If the router cannot find or start its operating system (called the Internetwork Operating System, or IOS), it will start in ROM mode--used to update or install a new operating system. In the even the system does load its operating system, it will load an available configuration file. If no configuration file is found, it will await manual configuration from the console, or if there are active network connections available, the 2500 series will attempt auto-configuration through those available network connections.
6.
Step 2

Begin the system configuration dialog. In the event that the configuration file is not found, or is invalid, and auto-configuration does not work, the unit will expect to be configured interactively, from the console port. The configuration dialog will include default answers for most questions posed to the operator. These default answers will appear in square brackets at the end of each question. Tapping the "Enter" key will accept the default answer.
7.
Step 3

Set passwords. There are two types of passwords possible for these models. There is an ordinary "enable" password which is stored in clear text in the configuration file, and an encrypted "enable secret" password. The enable password is used for some older software, and in those situations in which the enable secret password has not been set. There is also a separate password for the virtual terminal server, which helps protect the system from hackers dialing in through the auxiliary port modem.
8.
Step 4

Select protocols. The router is equipped to understand a variety of then-current protocols, including Banyan Vines, DECnet, Apollo and the Internet Protocol (IP). Also included are routing protocols which were used between routers to ensure coordination of the routing process.
9.
Step 5

Configure specific interfaces. Each port must also be explicitly configured. Significant understanding of the physical and logical layout of the LAN and WAN are assumed, so if you have questions about these settings, you should enlist the help of your network administrator. Misconfiguration of a router can corrupt communications across an entire network, so don't hesitate to stop the configuration process at any time and do additional research. The router will wait indefinitely for your return.
10.
Step 6

Once the interfaces are configured, the software will present you with the entire configuration and ask if you would like to use the configuration. Responding "yes" will write the configuration file into NVRAM as the new default configuration file used at start-up. To revisit the configuration, type "configure" at a command prompt on the running system.

Tips & Warnings

*
Research your settings in advance. Do not be afraid to step aside and do some additional research if you do not understand a question, or the implications of an answer.
*
Incorrectly configuring a router may have serious consequences on communications. Ensure your settings are accurate.
