So, doing a "sh bgp ipv6 uni 2400:cb00::/32 long" reveals that CloudFlare are currently announcing a bunch of /48s to the rest of the internet through nLayer only - as far as I can see. Simple suggestion: announce the /32 to the internet from all peering points like good Netizens and then announce your /48s from whatever peering it is you want the traffic sent to and tag it with the NO_EXPORT community attribute so you're not spamming up everyone's tables or hoisting yourselves by your own petard by getting filtered out. Kind Regards, Oliver
