<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">FWIW, the RFC6106 support that’s in IOS (big I) allows one to specify DNS Server Addresses but not, currently, the DNS Search List. As Lorenzo mentioned,
this is in the latest ASR1000 release, and will appear on other platforms over time as their releases pick up the latest version of ND. E.g. for the “T” release on ISRs, this is intended to ship in Q1CY14 – but as ever, contact your account team for committed
dates.<o:p></o:p></span></p>
