NAME

  AsconfAckWithAddUnknown.seq - ASCONF-ACK chunk is received with Error Cause indicating Add IP Address was not understood

PURPOSE

  To check that if ASCONF-ACK chunk is received with Error Cause indicating
  Add IP Address was not understood then the endpoint should consider the
  operation failed and MUST NOT attempt to send any subsequent Add IP Address
  requests to the peer.

SYNOPSIS

  ./AsconfAckWithAddUnknown.seq [-tooloption ...] -pkt ./AsconfAckWithAddUnknown.def
    -tooloption : v6eval tool option

            ../common/SCTP_COMMON.def

PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange the data
  in Endpoint B such that ASCONF message with Add IP Address is sent to
  Endpoint A.

TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

                                                   <-----    Asconf
                <-----------------      ASCONF
                                        (Add IP Address)
  ASCONF-ACK    ----------------->
  (Unrecognized Parameters)
                                                   <-----    Asconf
                <---no not send---      ASCONF
                                        (Add IP Address)

  TEST DESCRIPTION:

  1. Sending ASCONF message with Add 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 Add IP Address
     was not understood from endpoint A to B with Add IP Address.
  3. Check A: Endpoint B should consider the operation failed and MUST
     NOT attempt to send any subsequent Add IP Address requests to
     Endpoint A.

NOTE

  None

REFERENCE

  RFC 5061

  5.3.  General Rules for Address Manipulation

    When building TLV parameters for the ASCONF Chunk that will add or
    delete IP addresses, the following rules MUST be applied:

    F3a) If an endpoint receives an Error Cause TLV indicating that the
         IP address Add or IP address Deletion parameters was not
         understood, the endpoint MUST consider the operation failed and
         MUST NOT attempt to send any subsequent Add or Delete requests
         to the peer.

    F3b) If an endpoint receives an Error Cause TLV indicating that the
         IP address Set Primary IP Address parameter was not understood,
         the endpoint MUST consider the operation failed and MUST NOT
         attempt to send any subsequent Set Primary IP Address requests
         to the peer.
