<div dir="ltr">Hello,<div><br></div><div>In reviewing our BGP routing policies last week, I realized that we are advertising our address space upstream in slightly different ways to our two upstream providers.  For example, we might advertise a /21 to one provider and break that into two /22s when advertising it to the other.  (The reason this was done was to help with traffic engineering--we'd prepend one of the /22s to help balance the traffic.  Prepending the entire /21 might have been too much.)</div><div><br></div><div>I'm just wondering if that's acceptable practice, or if we should advertise consistent prefixes between providers?</div><div><br></div><div>Thanks,</div><div>Ben<br clear="all"><div><br></div>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div style="min-width:600px;width:100%;border:1px solid #fff"><table style="font-stretch:normal;line-height:normal;font-family:Arial;font-size:initial;color:rgb(99,99,99)"><tbody><tr><td valign="top" style="padding:0 8px 0 0"><a href="https://img.beta.newoldstamp.com/r/13887/p" target="_blank"><img src="https://img.beta.newoldstamp.com/p/13887" style="display:block" width="125"></a></td><td style="color:rgb(0,111,173);font-stretch:normal;font-size:80%;line-height:normal;font-family:Arial;padding:0px 8px" valign="top"><div style="color:#0070af;font-size:1.3em;font-weight:bold">Ben Logan</div><div style="white-space:nowrap!important"><span style="color:#636363;font-size:1.1em;font-style:italic">Senior Network Engineer | Working Lead</span><div style="color:#636363;font-size:.9em;font-weight:bold">Wilkes Communications | RiverStreet Networks</div><div style="font-size:10px;line-height:10px"> </div><div><span style="font-size:1em">Address: </span><span style="color:#636363;font-size:.9em">1400 River St Wilkesboro, NC 28697</span></div><div><span style="font-size:1em">Email: </span><a href="mailto:benlogan@myriverstreet.net" style="color:rgb(99,99,99);font-size:0.9em" target="_blank">benlogan@myriverstreet.net</a></div><div><span style="font-size:1em">Phone: </span><span style="color:#636363;font-size:.9em">336-973-9075</span></div><div><span style="font-size:1em">Mobile: </span><span style="color:#636363;font-size:.9em">336-452-8072</span></div><div><span style="font-size:1em"> </span><a href="https://www.wilkes.net" style="color:rgb(99,99,99);font-weight:bold;font-size:0.9em" target="_blank">wilkes.net</a></div><div><span style="font-size:1em"> </span><a href="https://www.myriverstreet.net" style="color:rgb(99,99,99);font-weight:bold;font-size:0.9em" target="_blank">myriverstreet.net</a></div></div></td><td style="color:#006fad;padding:0 0 3px 6px;width:42px;border-left:3px solid" valign="middle"><table><tbody><tr><td><a href="https://img.beta.newoldstamp.com/r/13833/facebook" target="_blank"><img src="https://img.beta.newoldstamp.com/i/1/1/0/006fad/55.png" width="32"></a></td></tr><tr><td><a href="https://img.beta.newoldstamp.com/r/13833/twitter" target="_blank"><img src="https://img.beta.newoldstamp.com/i/1/1/0/006fad/197.png" width="32"></a></td></tr><tr><td><a href="https://img.beta.newoldstamp.com/r/13887/youtube" target="_blank"><img src="https://img.beta.newoldstamp.com/i/1/1/0/006fad/224.png" width="32"></a></td></tr><tr><td><a href="https://img.beta.newoldstamp.com/r/13833/linkedin" target="_blank"><img src="https://img.beta.newoldstamp.com/i/1/1/0/006fad/106.png" width="32"></a></td></tr><tr><td><a href="https://img.beta.newoldstamp.com/r/13833/instagram" target="_blank"><img src="https://img.beta.newoldstamp.com/i/1/1/0/006fad/98.png" width="32"></a></td></tr></tbody></table></td></tr></tbody></table><div style="font-size:5px;line-height:5px"> </div><br><table style="max-width:570px"><tbody><tr><td colspan="3" style="font-stretch:normal;font-size:10px;line-height:normal;font-family:Arial;font-style:italic;color:rgb(99,99,99)">This email transmission contains information which may be confidential and/or privileged. The information is intended to be for the use of the individual or entity named on this transmission. If you are not the intended recipient, be aware that any disclosure, copying, distribution or use of the contents of this email information is prohibited. If you have received this email in error, please notify the sender to arrange for retrieval of the original documents. Thank you.</td></tr></tbody></table></div></div></div></div></div></div></div></div></div></div>
