Test v6LC.2.1.1 - On-link Determination
Part B: Global Address, On-link Prefix covers TN1
Verify that a node correctly determines that a destination is on-link.
* [IPv6-ARCH] Section 2.4
* [ND] Section 5.2
* Packet generator
* Monitor to capture packets
No Common Test Setup is performed. If the NUT is a router, configure a default route
with TR1 as next hop. The Common Test Cleanup is performed after each part.
Packet A
IPv6 Header
Next Header: 58
Source Address: TN1's Link-local Address
|
| ICMPv6 Echo Request |
|
Packet B
IPv6 Header
Next Header: 58
Source Address: TN1's Global Address
|
| ICMPv6 Echo Request |
|
Router Advertisement
IPv6 Header
Next Header: 58
|
Router Advertisement
Prefix Length: 64
L Bit: 1 (on-link)
Prefix: TN1's Global Prefix
|
Packet C
IPv6 Header
Next Header: 58
Source Address: TN2's
Global Address
Destination Address: NUT's Global Address
|
| ICMPv6 Echo Request |
Part B: Global Address, On-link Prefix covers TN1
3. If the NUT is a host, TR1 transmits the Router Advertisement. The Prefix Advertisement covers
TN1's global address.
4. TN1 transmits Packet B, an Echo Request with TN1's global source address.
5. Observe the packets transmitted by the NUT.
Part B
Step 5:
TN1's global address is covered by the on-link prefix. Hence, the NUT should
consider TN1's global address as on-link. The NUT should send a Neighbor Solicitation with
Target Address equal to TN1's global address, indicating that the NUT has successfully
determined that TN1 was on-link.
* None.
