Gurpreet,

we have implemented the AddIP extension in the sctplib
developer version, which is sctplib-1.1.6 -- also see
http://freshmeat.net/projects/sctplib/?branch_id=45192
for reference.

This version should work together with the latest release
of the socketapi-library.

Then, if you are on a linux system, and have the netlink
routing messages enabled (I haven't tested that yet on
2.6. kernels): try establishing an association between
a client and a server, for both of which you choose
INADDR_ANY as local addresss.

If you add an interface to one of the instances (e.g.
by calling "ifconfig eth1 W.X.Y.Z netmask 255.255.255.0
broadcast W.X.Y.255 up" - or something similar), you should
be able to trace ASCONF chunks.

Please note that this has been somehwat tested, but is
still an experimental implementation.

Please let me know whether that worked (or not).

Best regards,
Andreas
