allow me to rant a little bit. I think if IOS was decently coded to
begin with we did not
need to spend all this time writing all these tools !!!
how trivial could it be to check for an existance of a filter before
applying it ???
same for other filter maps reference and MQC
I am willing to spend the time on filter_audit tool because the given
situation is that we
have many IOS devices and I don't see IOS fixed very soon (although XR
already available).

not sure I fully understand, you mean check for duplicate IP address ?
AFAIK, IOS will not allow to use duplicate IP on same router, or will
issue a warning
regarding duplicate IP on multiple devices, IOS will generate an error
log which I use to generate email alert, works ok for us.
