LAB 2-1 EIGRP CONFIGS AND EXPLANATIONS  

Friday, September 19, 2008

This is the lab topology with configs ..... i do paste this configs because its a kind of back up for me and its a kind of good practise for people who try in future to just copy and paste these configs...

















so to start of with this is the topology ... this is straight from cisco lab guide edition version 5 bsci ...

theres a mistake in printing ip addresses 10.1.100.0/24 belongs to fa0/0 of r1
10.1.200.0/24 belongs to s1/0 of r1



so to start of with the given question and objectives :

LAB 2-1

LEARNING OBJECTIVES

1.Configuring EIGRP on an Interface

2.Configuring Bandwidth command to limit Eigrp bandwidth

3.verify Eigrp adjacencies

4.verify eigrp routing info exchage

5.utilize debugging commands for troubleshooting EIGRP

6.CHALLENGE: TEST covergence when topology change occurs



SCENARIO

You are responsible for configuring the new network to connect your companys engineering , Marketing and accounting departments
represented by loop back interfaces on three routers . the physical devices have just been installed and connected by fast ethernet
and serial cables . Your task is to configure eigrp to enable full connectivity between all departments


i will be following by my ideas , staratagies and way i thought and problems faced after this message .. so these are the configs

tcl script for testing ping connectivity
these are becoming handy for me .. write all of you ips in a note pad and the method is as mentioned in above posts

to stop the bloody ping use ctrl + ^ key combinaition .. i called it bloody because i dint knew the
key and had to stop and start router thrice ... ehehehe



this is my first lab . the following messages follows how i approahed
