RE: Sending ABORT upon receipt of INIT-ACK

Brian,

Thanks...I did see this in the rfc4460.  I guess the server really can't
do anything with the ABORT since it doesn't have a TCB.  However, I
guess it might help in debugging in trying to determine why an
association is not coming up.

Regards,
Lincoln

Lincoln,

Because such an ABORT may be blocked by firewalls for security reasons
(e.g.
port scanning), the 2960bis documents downgrades the MUST to SHOULD in
all cases and permits an implementation to not send the ABORT in the
scenarios described.
