> AS_PATH is used to specify the path that the payload takes. really? i thought it was a routing loop detection mechanism. it's been a while since folk wrote research papers describing schemes for routing by AS.
i would phrase it as AS_PATH specifies the ASs through which the routing announcement has passed. > Signed_AS_PATH is to verify the path that the update message takes. and then this works really nicely. > There is no reason they can not be different. and here i thought that detecting that they differ, as an attack, is the core goal of as-path validation. randy _______________________________________________ sidr mailing list sidr@ietf.org https://www.ietf.org/mailman/listinfo/sidr
