Part B: Send Redirect to Alternate Router
Verify that a router properly handles transmission of Redirect messages.
* [ND] Sections 8.2
* Packet generator
* Monitor to capture packets
Common Setup 1.1 is performed at the beginning of each test part. The Common Test
Cleanup Procedure is performed after each part.
i. TN2 is an on-link neighbor on Link B to TN1 (instead of residing on Link A
depicted in Common Topology).
ii. RUT advertises prefix X on Link B.
Part B: Send Redirect to Alternate Router
3. Configure TN2 to be an off-link neighbor residing on Link A as depicted in the Common
Topology.
4. TN1 transmits an Echo Request to TN2's unicast global address and a first hop through the RUT.
5. Observe the packets transmitted by the RUT.
Part B
Step 5: The RUT should transmit a Redirect message with the following values:
IPv6 Hop Limit 255
IPv6 Source Link-Local address of RUT
IPv6 Destination TN1's address (used in Echo Request's Source Address)
Target TR1's link-local address
Destination TN2's unicast global address
TLL Option TR1's link-layer address if known
Redirected Header TN1's Echo Request without total packet exceeding 1280
bytes.
* The RUT may not support the generation of Redirect messages.
