Test v6LC.2.1.6 - Neighbor Solicitation Origination, Reachability Confirmation
Part B: Neighbor Solicitation Origination, Global => Global
Verify that a node properly originates Neighbor Solicitations when trying to confirm the
reachability of a neighbor.
* [ND] Section 7.3
* Packet generator
* Monitor to capture packets
Perform Common Test Setup 1.1 with a Retransmit Interval value of 1 second before
each part. The Common Test Cleanup Procedure is performed after each part.
The Reachable Time is 30 seconds in the Router Advertisement transmitted by TR1 in Common Test
Setup 1.1.
Packet A

Part B: Neighbor Solicitation Origination, Global => Global
8. TN1 transmit Packet B. The source address is TN1's global address and the destination address is
the NUT's global address.
9. Observe the packets transmitted by the NUT. TN1 sends a Neighbor Advertisement upon
receiving Neighbor Solicitations from the NUT.
10. Wait REACHABLE_TIME * MAX_RANDOM_FACTOR seconds so that the NCE of TN1
transit to state STALE.
11. TN1 transmits Packet A. The source address is TN1's global address and the destination address
is the NUT's global address.
12. Observe the packets transmitted by the NUT.
13. Wait DELAY_FIRST_PROBE_TIME seconds so that NCE of TN1 transit to state PROBE.
14. Observe the packets transmitted by the NUT.
Part B
Step 9:
In response to Packet B, the NUT should transmit Neighbor Solicitations with a
Target Address equal to the TN1's global Address at intervals of 1 second. The NUT MUST
transmit no more than 1 Neighbor Solicitation every 1 second. Once a Neighbor
Advertisement is received from TN1, the NUT should send an Echo Reply in response to
Packet B. The NCE of TN1 is in state REACHABLE.
Step 12:
In response to Packet B, the NUT should transmit an Echo Reply.
Step 14:
The NUT should transmit Neighbor Solicitations with the NUT's global or link-
local address being the source address and TN1's global address as the destination address.
The maximum number of Neighbor Solicitations that the NUT can transmit is 3.
* None.
