Hi: I am interested in ur question to nanog about doubting whether AS 49463 is reachable thourgh AS 12670. in ur case, AS 49463 is multihomed. what you want to do,if i am right, is that you wanna make the following things happen: the 213.215.28.0/23 is reachable both through AS 12670 and AS 13193. And like what u said, you are certain that that prefix is announced to AS 12670. So all the customers of AS 12670 should be ok to reach that prefix. Am I right? I have a question: if the link between 13193 and 4943 fails, what will happen? will the guy: Nicolas DEFFAYET lose the reachability to AS 49463?

Hi, Since i do have direct connectivity to 13193 and 12670, if my prefix is correctly announced through both ISP, the failure of 1 ISP should allow me to still be reachable and reach the outside world. Laurent
