I’m trying to add two sub-options 193, to send two IP-addresses.</div><div>In ISC I can do the following:</div><div><span style="font-size: 10pt; caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Calibri, sans-serif;"><br></span></div><div><span class="Apple-tab-span" style="white-space: pre;"> </span>option space VI_OPTION code width 4 length width 1 hash size 1;</div><div><p class="MsoNormal" style="margin: 0cm 0cm 0cm 36pt; font-size: 10pt; font-family: Calibri, sans-serif; caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><span></span></p><span><span class="Apple-tab-span" style="white-space:pre"> </span>option VI_OPTION.option code 3561 = array of{unsigned integer 8, unsigned integer 8, unsigned integer 8, unsigned integer 8, ip-address};</span></div><div><span><span class="Apple-tab-span" style="white-space:pre"> </span>option space VI_VSO code width 1 length width 1 hash size 4;</span></div><div><span class="Apple-tab-span" style="white-space: pre;"> </span>option VI_VSO code 125 = encapsulate VI_OPTION;</div><span><div><span><br></span></div>And then construct the Option:<br></span><span> vendor-option-space VI_VSO;<br> vendor-option-space VI_OPTION;<br> option VI_OPTION.option 193 6 16 4 w.x.y.z;<br> 193 6 16 4 v.w.x.y;</span><div></div><div><span><br></span></div><div><span>This will look like the following in wireshark:</span></div><div><img alt="PastedGraphic-1.png" src="cid:DF36ED1D-6EE6-4477-8823-33175DB1CB8D"></div><div><br></div><div>I cannot reproduce this behaviour in Kea.
