AsconfAckWithAddSuccess.seq - ASCONF-ACK chunk is received with Success Indication parameter indicating Add IP Address success
To check that if ASCONF-ACK chunk is received with Success Indication parameter indicating Add IP Address success then the endpoint should consider the address part of the existing association.
./AsconfAckWithAddSuccess.seq [-tooloption ...] -pkt ./AsconfAckWithAddSuccess.def -tooloption : v6eval tool option See Also: ../common/STD_PKT_COMMON.def ../common/SCTP_COMMON.def
Association is established between endpoint A and B. Arrange date in endpoint B such that ASCONF chunk with Add IP Address Parameter is sent to endpoint A.
Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED)

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 Success Indication parameter indicating Add IP Address success from endpoint A to B. 3. Check A: Endpoint B should consider the address part of the existing association.

ASCONF-Request Correlation ID: 32 bits
This is an opaque integer assigned by the sender to identify each request parameter. The receiver of the ASCONF Chunk will copy this 2-bit value into the ASCONF Response Correlation ID field of the ASCONF-ACK response parameter. The sender of the ASCONF can use this same value in the ASCONF-ACK to find which request the response is for. Note that the receiver MUST NOT change this 32-bit value.
Address Parameter: TLV
This field contains an IPv4 or IPv6 address parameter as described in Section 3.3.2.1 of [RFC4960]. The complete TLV is wrapped within this parameter. It informs the receiver that the address specified is to be added to the existing association. This parameter MUST NOT contain a broadcast or multicast address. If the address 0.0.0.0 or ::0 is provided, the source address of the packet MUST be added.
