We have cisco config analyser (it built the object tree) but it's not 
more than BETA. I have idea to write good self-edicated analyser but this 
idea is discussed only now.

Anyway, any sources (library on the PERL, I think) helping to build such 
checkers and analysers will be appresiated. It's not too difficult to 
built such analyser, but it's nessesary to keep config data base 
up-to-date because IOS changes every day...

THis analyser was written by Julia Pasynkova, you can ask her by e-mail 
(julp at - the ideas was of me and of her, and the code (on 
the PERL) was written by her. But I think it's model only because it does 
not use external data base we can to keep up-to-date.

Unfortunately, our attempts to search such tools resulted to nothing.
