<p class="MsoNormal"><span style="font-size:11.0pt">Hey all, in 2014 I ran into an issue where I converted an MLXe to the ipv4-ipv6-2 profile to get maximum routes for both. When I did that, I lost management access because I use management VRF’s, and those
require resources from the ‘IPv4 VPN’ segment of CAM. The ipv4-ipv6-2 profile sets that to zero. So, I switched to multi-service-4 as a workaround since it still had enough room.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Fast forward two years and IPv6 adoption has increased to the point where an MLXe with –X cards is just about out of CAM if it’s acting as an internet router and using the multi-service-4 profile. Starting
to see these alerts:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal" style="line-height:11.25pt"><span style="font-size:9.0pt;font-family:Helvetica;color:#666666">Aug 31 11:51:10:A:CAM IPv6 partition warning: total 32768 (reserved 0), free 1602, slot 3, ppcr 1<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">because internet routers are seeing roughly 31,000 IPv6 advertisements now and multi-service-4 only has room for 32k.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">At the time, there was no way to configure custom CAM values, such as my desired goal of 768k minus 1 ipv4, 64k ipv6, 1 IPv4 VPN to facilitate one VRF. I didn’t want to use ipv4-ipv6-2 either since I like
having the VRF.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Is there any workaround for this issue in later code releases?<o:p></o:p></span></p>
