Hello Chris,<div><br></div><div>CloudFlare operates a discontiguous network and we are unable to announce the /32.</div><div><br></div><div style>The /48 is a valid announcement for the global table. While we understand there are some concerns about de-aggergation, aggregation is not possible and we would either be announcing the deaggregated address space from a single assignment, or we'd have multiple assignments for the same purpose, so the impact on the routing table would be the same.</div>
<div style><br></div><div><span style>If the full table can not be accepted, I would recommend installing a default route to one or all of your upstreams, otherwise many parts of the global table will not be reachable, not just to CloudFlare.</span> </div>
<div><br></div><div>Thanks,</div><div>Tom<br><br><div class="gmail_quote">On Fri, Jun 15, 2012 at 8:57 AM, Chris Welti <span dir="ltr"><<a href="mailto:chris.welti@switch.ch" target="_blank">chris.welti@switch.ch</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">This could be because there is no covering 2400:CB00::/32 route by Cloudflare in the global IPv6 routing table.<br>
There is only 2400:CB00:2048::/48 and this might be filtered by ISPs due to the APNIC miniumum allocation size of /32 for 2400::/12.<br>
Cloudflare must announce at least the covering /32 for it to be globally reachable.<br>
