Excellent! That was exactly the answer I was looking for.

Thus, a /23 you announce in Site B would take precedence over the HQ /20 announcement. Traffic bound to IP's outside of that /23 would end up going to your HQ where /20 is being announced. james -----Original Message----- From: Jim Barstow [mailto:jimb-clec@dssitech.com] Sent: Wednesday, February 28, 2007 1:45 PM To: isp-bgp@isp-bgp.com Subject: [isp-bgp] BGP announcement question I have been googling for the answer to this, but couldn't find it. I have ARIN PI space at my an ASN in my headquarters location. It announces the /20. I now have a new location that is not on my attached network, thus, it has its own upstream peers and whatnot. Can I announce a smaller /23 from my /20 from the new location? Will the remainder of the /20 continue to go towards my existing ASN? I don't know if there is some "glue" that ties my /20 to my primary sites ASN. ------------------------------------ SmartTel Communications Jim Barstow Sr. Telecom Engineer jimb@smarttelco.com PO Box 367 22645 Canal Road Suite E Orange Beach, AL 36561 tel: (251) 224-0868 fax: (251) 224-0830 mobile: (251) 747-4913 ------------------------------------ mailto:remove-isp-bgp@isp-bgp.com To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
