NAME

  AsconfAckDuplicate.seq - ASCONF-ACK chunk is received with duplicate current Sequence Number while ASCONF Chunk is outstanding

PURPOSE

  To check that if ASCONF-ACK chunk is received with duplicate current
  Sequence Number then the endpoint discard the ASCONF-ACK chunk.

SYNOPSIS

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

PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange the date
  in endpoint A such that ASCONF-ACK chunk with duplicate current
  Sequence Number is sent to endpoint B.

TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

  ASCONF-ACK    ----------------->      Discard
  (duplicate current Sequence Number)

  TEST DESCRIPTION:

  1. Send ASCONF-ACK chunk from endpoint A to B with duplicate current
     Sequence Number while ASCONF Chunk is outstanding.
  2. Check A: ASCONF-ACK chunk should be discarded at endpoint B.
