Is 213.215.28.0/23 (AS 49463) announced through AS 12670 and AS 13193
Hi, I did set-up this netblock behind two pipes. One on AS13193 (which is working flawlessy), and ahother on AS12670 (which I doubt of). Can please any of you tell me if from your location 213.215.28.0 is reachable through AS12670 ? Thanks Laurent

Hi, I'm of course announcing it to their upstream router. If their upstream router actually forwards it to its neighbors is another question...which I can't unfortunately not answer. But I guess the announce is not propagated outside of their network... Thanks for your help. Laurent
