Test Setup

  No Common Test Setup is performed. Wait at least 3 seconds

  previous NCE's are in state No NCE. The Common Test Cleanup procedure is performed after each part.
                        1. Configure the RUT to advertise prefix X on Link B.
                        2. Configure an address with prefix X on the RUT.


Procedure

  1. TN1 transmits a Neighbor Solicitation to the RUT's Subnet-Router anycast address.
  2. Observe the packets transmitted by the RUT.


Observable Results

  Step 2:
  The RUT should respond to TN1 by sending a Neighbor Advertisement between 0 and
  MAX_ANYCAST_DELAY_TIME after it receives the Neighbor Solicitation. The RUT's Neighbor
  Advertisement should contain a value of 0 in the override flag field.
