=head1 NAME

  AsconfAckWithDelError.seq - ASCONF-ACK chunk is received with Error Cause indicating Delete IP Address operation failed

=head1 PURPOSE

  To check that if ASCONF-ACK chunk is received with Error Cause indicating
  Delete IP Address operation failed then the endpoint should not delete the
  address from the association.

=head1 SYNOPSIS

=begin html
<PRE>
  <A HREF="./AsconfAckWithDelError.seq">./AsconfAckWithDelError.seq</A> [-tooloption ...] -pkt <A HREF="./AsconfAckWithDelError.def">./AsconfAckWithDelError.def</A>
    -tooloption : v6eval tool option

</PRE>

=end html

=head1 PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange the date
  in endpoint B such that ASCONF chunk with Delete IP Address Parameter
  is sent to endpoint A.

=head1 TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

                                                   <-----    Asconf
                <-----------------      ASCONF
                                        (Delete IP Address X)
  ASCONF-ACK    ----------------->
  (Error Cause Indication)
  HEARTBEAT     ----------------->
  (IP Address X)
                <-----------------      HEARTBEAT-ACK
                                        (IP Address X)

  TEST DESCRIPTION:

  1. Sending ASCONF message with Delete IP Address Parameter from
     endpoint B to A.
     Record the message sequence using a signal emulator.
  2. Send ASCONF-ACK message with Error Cause indicating Delete IP
     Address operation failed from endpoint A to B with Delete IP
     Address.
  3. Check A: Endpoint B should not delete the IP Address for Delete
     IP Address Parameter.
