Test v6LC.2.3.8 - Invalid Option (Hosts Only)
Part A: Path MTU Option
Verify that a host ignores invalid options in Redirect messages and processes the remainder of
the Redirect normally.
* [ND] Section 8.1
* [ICMPv6] Section 2.4
* Packet generator
* Monitor to capture packets
The following setup procedure is performed before each Part:
a) Perform Common Setup 1.1.
b) TR2 transmits an Echo Request to the HUT's link-local address. TR2 responds to any
Neighbor Solicitations from the HUT with a Neighbor Advertisement with the solicited bit set to
1 causing the HUT to update it's NCE for TR2 to sate REACHABLE.
The Common Test Cleanup Procedure is performed after each part.
Part A: Path MTU Option
1. TR1 forwards an Echo Request from TN1 to the HUT. The Source Address is the off-link global
address of TN1. The Destination Address is the global address of the HUT.
2. Observe the packets transmitted by the HUT.
3. TR1 transmits a Redirect message to the HUT. The ICMPv6 Destination Address is the global
address of TN1. The Target Address is the link-local address of TR2. The Redirect message
contains a Path MTU option.
4. TR1 forwards an Echo Request from TN1 to the HUT. The Source Address is the off-link global
address of TN1. The Destination Address is the global address of the HUT.
5. TR2 transmits a solicited Neighbor Advertisement in response to any Neighbor Solicitations from
the HUT.
6. Observe the packets transmitted by the HUT.
Parts A-C
In all Parts, the HUT should respond to the first Echo Request using TR1 as a first hop. The
HUT should respond to the second Echo Request using TR2 as a first hop, indicating the
HUT ignored the invalid option and processed the Redirect message.
* None.
