Hi Alex and Ruediger,

To continue our discussion at the meeting, let's use the example you provided yesterday. Both lateral peering between AS1-AS2, and AS2-AS3.

First question, does AS1 or AS2 sign any ASPA object for this pair and how?  I see description for Sibling relation representation in Section 7, but haven't been able to find any for P2P.

Second question, if yes to the above question, how does AS 3 use any of the ASPA object(s) to detect the leak? And if no, how to detect the leak anyway?

Thanks.

Yunan
