IOU Lab Topology #2

As I mentioned in my first IOU topology post I more frequently use another topology that has turned out to be better suited for my labbing needs than my first attempt.  Well, here is that topology.

This time there 9 routers with one acting as a dedicated Frame Relay switch, and plenty of links to create anything that I've come across in my CCIE studies so far.  To get this bad boy up and running you'll need the NETMAP file:

1:0/0 3:0/0
1:0/1 2:0/1
2:0/2 3:0/2
2:0/3 6:0/3
3:0/1 7:0/1
1:0/2 4:0/2
4:0/3 8:0/3
2:1/0 100:0/0
2:0/0 4:0/0 6:0/0
3:1/0 100:0/1
3:1/2 5:0/2
3:1/1 5:0/1
5:1/1 7:1/1
6:0/2 7:0/2
5:1/2 7:1/2
6:1/0 100:0/2
6:0/1 8:0/1
7:0/0 8:0/0
7:1/0 100:0/3

And since I already have it here is the necessary configuration for the Frame Switch to match the DLCI legend on my diagram:

One last thing on this.  Since there are different combinations of interfaces on the different routers in the topology I created myself a little Bash script that i use to start up each router.  I usually run things inside a Gnu Screen session with one window for each router, and I use this script to get things running.  It's pretty self explanatory, and you may need to edit the paths to make it work for you environment.

#!/bin/bash 

#################################
#                               #
# Simple startup script for IOU #
#                               #
#################################

if [ $# = 0 ]; then
    echo "usage: ./iou_start_up "
    echo " "
    echo "Valid routers to start are 1 - 9 or frs"
    echo ""
    exit 1
fi

case $1 in
    1 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 0 1 ;;
    2 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 1 2 ;;
    3 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 1 3 ;;
    4 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 0 4 ;;
    5 ) /path_to/i86bi_linux-adventerprisek9-ms -e 0 -s 2 5 ;;
    6 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 1 6 ;;
    7 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 1 7 ;;
    8 ) /path_to/i86bi_linux-adventerprisek9-ms -e 1 -s 0 8 ;;
    frs ) /path_to/i86bi_linux-adventerprisek9-ms -e 0 -s 1 100 ;;
    * ) echo "invalid selection" ;;
esac

 That about covers it.  If you use this and like it please let me know.

*UPDATE*

I've added a few more links in, and the NETMAP and diagram have been updated.
