Test v6LC.2.1.1: On-link Determination
Part C: Global Address, On-link Prefix does not cover TN2
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 C: Global Address, On-link Prefix does not cover TN2
6. If the NUT is a host, TR1 transmits the Router Advertisement. The Prefix Advertisement does not
cover TN2's global address.
7. TN2 transmits Packet C, an Echo Request with TN2's global source address.
8. Observe the packets transmitted by the NUT.
Part C
Step 8:
TN2's global address is not covered by the on-link prefix. Hence, the NUT should
consider TN2's global address as off-link. The NUT should send a Neighbor Solicitation
with Target Address equal to TR1's link-local address indicating that the NUT has
successfully determined that TN2 was off-link.
* None.
