Description of the Tests
You will all go through these steps sooner or later, but I thought I’d share my first tries with you.
I started out with two hosts. One host is a Windows 2000 machine running the Microsoft Research stack. I called this host Marvin. The second host is a SuSE Linux host, also running an IPv6 stack. That host’s name is Ford. Communication between the two hosts has not been an issue. In the absence of a router, they both autoconfigured for a link-local IPv6 address, using the 48-bit MAC identifier to build the address.
The Windows 2000 host Marvin has the following configuration:
|
MAC address |
00-02-B3-1E-83-29
|
|
IPv4 address |
|
|
IPv6 address |
fe80::202:b3ff:fe1e:8329
|
The Linux host Ford has the following configuration:
|
MAC address |
00-A0-24-C5-32-56
|
|
IPv4 address |
|
|
IPv6 address |
fe80::2a0:24ff:fec5:3256

Pinging with IPv6
The first success was the verification of IPv6 communication by pinging each host as follows.
Open a command window on Marvin and issue the following command:
ping6 fe80::2a0:24ff:fec5:3256
Do you want to know what a ping with IPv6 looks like? Have a look at Figure 11-6.

Frame 1 is the Echo Request from Ford; Frame 2 is the Echo Reply from Marvin. The screenshot shows the two MAC addresses configured for a link-local ...
