Sheng's original question of which I was replying to, was in an outage situation where another AS is claiming ownership of your net block what <span style="font-style: italic">actions</span> could be taken to enable resumption of service. This style of discussion is something I'm interested in hearing about, other than nag the upstreams which is slow at best. Actions that can be taken by the AS in question to resume service.</div><div><br></div><div>Yes, let's think of the TCAM, but let's try resume service first. If Telstra accept the route (and my hunch is they will), sort that out before trying to work out Layer 8.</div><div><br></div><div>Any other creative solutions on how to gain control back of one's prefixes?</div><div><br></div><div>Cheers,</div><div><br></div><div>Wade</div><div><div><div><div><br></div></div></div></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> Matthew Moyle-Croft <<a href="mailto:mmc@mmc.com.au">mmc@mmc.com.au</a>><br><span style="font-weight:bold">Date: </span> Tue, 1 May 2012 20:35:56 -0700<br><span style="font-weight:bold">To: </span> James Spenceley <<a href="mailto:james@vocus.com.au">james@vocus.com.au</a>><br><span style="font-weight:bold">Cc: </span> Wade Millican <<a href="mailto:wade.millican@echoent.com.au">wade.millican@echoent.com.au</a>>, "<a href="mailto:ausnog@ausnog.net">ausnog@ausnog.net</a>" <<a href="mailto:ausnog@ausnog.net">ausnog@ausnog.net</a>><br><span style="font-weight:bold">Subject: </span> Re: [AusNOG] Issue getting routes from Telstra to 49.156.16.0/22<br></div><div><br></div><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>James,</div>Please don't encourage de-agg to /24 and below.
