TCL Scripting in IOS. Easy to understand Tutorial !

Hi all. Here i am with yet another tutorial. Programming in IOS. Dont confuse it with programming IOS because you cant do it. IOS is not open source so you cant make extensions/modifications to it, But IOS allows you to use TCL ( pronounced "tickle" ) scripting language to write scripts to get tasks done in a different and more feasible way, that was either not possible before or too complicated. One example is the recent query posted by our fellow member superr about how to monitor snmp OID to trigger events. Although the solution was in EEM, but the same could be done using tcl. Those who are totally new to this stuff will be getting confused as to what i am talking about. So lets see a few examples, that are very practical and you may encounter tasks similar to these more often. Example 1) When router cpu utilization reaches 30%, send an email to me, plus give only the first five top processes in "sh process cpu sorted". Example 2) (this is a case of

GNS3-Topology: CCNA & CCNP Full Mesh Topology Template

Chris sent me a lab which he says has helped him to work on about 95% of his CCNA and CCNP lab requirements. I think this is a clear sign that using Dynamips or GNS3 can be effective in a big way with exam preperation. That 5% left over can be achieved in a few ways - rack space, friends with labs or purchasing switches on ebay and link them into the virtual topology using real interfaces. Nevertheless Its great to see how much we can do without cash, space or budget (electricity bill) to prepare ourselves for these exams. This lab is just a template lab and has no configs, routing protocols or scenarios to it. I’ll let Chris explain I created one simple topology that seems to handle 95% of my CCNA & CCNP lab requirements.  It isn’t fancy, but it should save people an hour+ of labor (that is how long it took me to create this topology). I was getting tired of making one lab per exercise in the Cisco Lab Portfolios and the Certification Zone lab exercises.  So I whipped up a 6 rout
