my variable '$bgp_ip' still has no value
I just re-downloaded the code from the root node and ran it, the only change I made was to add a print of $bgp_ip, and that variable is definitely not empty. So either the code you have posted here is not the code you are running, or there is some other mistake - for example, perhaps you have a typo in the variable name that is not being caught due to a missing strict. Please either post the actual code you are running or use the tips from the Basic debugging checklist to hunt down the problem in your code.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
