<p class="MsoNormal" style="margin-left:.5in">Hi all,<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I have a community set for a customer that is in the format target:ASN:x x being a range from 1-151. I need to setup a BGP export filter that will match all of the communities and only export these routes. If
I use standard communities ASN:x then I can use this format and it works:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">community "CUST-EXPORT" members "^ASN:(.*)$"<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">This does not work for extended communities.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Does anyone know how to make this work for extended communities? Reading the ALU docs I should be able to reg-ex for these types of communities, but have not been successful.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I have tried these formats but I get invalid format:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">community "CUST-EXPORT" members target:"^ASN:(.*)$"<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">community "CUST-EXPORT" members target:"ASN:*"<o:p></o:p></p>
