Re: [Tsvwg] I-D ACTION:draft-ietf-tsvwg-addip-sctp-11.txt

Hi Sal,

why not just use the correct addresses dring setup? If
one of the addresses is not valid anymore it can not be
used for DATA transfer, because it will not be verified.

And the SCTP chunk authentication, which is now required
for ASCONF/ASCONF-ACK chunks needs the 4 way handshake
to establish a shared key. See
http://www.ietf.org/internet-drafts/draft-tuexen-sctp-auth-chunk-03.txt

Best regards
Michael
