[TOLGA]No, one SCTP endpoint = one ASP/IPSP

[TOLGA]ASP-Id is not to identify ASPs using the saem SCTP associtiaon but to
identify ASPs which use dynamic addresses.

[TOLGA]What about ASPAC? How will you distinguish, which ASP has sent the
ASPAC, ASPDN, ASPIA? Also, what is the use of such a setup?

[TOLGA]As far as I can see, it won't work according to the procedures
defined in the RFC/IG. There is no ASP identifier in the messages -except
optional ASP-Id for ASPUP-, because it is assumed that this is known based
on the SCTP association the messages are received from.
