This is an FAQ, check the archives for many requests to do this kind of
thing on many devices.

Basically, check @command table in mtrancid for the command that
produces that output, identify the sub that deals with the output and
add your custom bit in the body of the while loop:

To discard the changing part, something like

/^(set address=/S+/s/S+).*$/ &&
  ProcessHistory(xxxxxxxxxxxxxx) && next;

To discard the line entirely:

/^(set address=/S+/s/S+).*$/ && next;


I'm not familiar with Microtik to be able to say what goes in the
ProcessHistory call marked "xxxxxxxxxxxxxxx". If you want to use that
first snippet, you can probably copy-paste the existing ProcessHistory
call towards the end of the while loop.

It's very obvious with a little perl- and regex-fu how it should all go
together


Disclaimer: Those regexes may or may not work :-)  I typed them without
having a reference handy and we all know that a regex is defined as "a
programming construct that is guaranteed to fail the first 5 times you
try get it right"
