Hi All,

    My impression on below setting is, ASP and one SG reside in the same
device since one ASP end association contains IP2 as an alternative path
which is used for the second association as the destination address.
     
    If i am not wrong, the association configuration at ASP end must match,
since the  same association will communicate to SG 2.
