Setting up 4 Cisco Routers in a Lab Envt.

[skhirbash]

Hi,

I want to setup 4 Cisco routers(3 2500s, and 1 2600) in a lab environment and have the following questions:

1- The 2500 routers have 56K DSU/CSU modules in each one of the them and T1-DSU/CSU module in one of them, what type of cables do I need to use to connect all of these routers?

2- Do I need to do anything when cofiguring the Serial interfaces?

Your response is very much appreciated.

Thanks,

sK

You first need to have an idea on how you want to connect your routers. To connect two routers on the 56K DSU/CSU port you need a crossover cable 1-7, 2-8, 7-1, 8-1

This is just a simple learing lab. I would like to setup the routers as follows:

Router1--LAB_A s0(56K DSU/CSU) to connect to Router2--LAB_B s0(T1 DSU-CSU). And Router2--LAB_B s1(56K DSU/CSU) to connect to Router3--LAB(56K DSU/CSU).

This is it! Thanks in advance.
