I think that the lab will be fairly specific about which method is desired.
Some, apparantly they just let the router figure out its own EUI-64 host
address, others it must have been defined.
Even for the ones you are supposed to use EUI-64, you still have some
control. That information is inheritied from the link-local address. If
you pre-define your link-local address, you can tweak any other addresses.
For example. On R2, every IPv6 interface, I would put:
Ipv6 address fe80::2 link-local
And later, if I added:
Ipv6 address 2001:192:10:1::/64 eui-64
When I went to look at "show ipv6 interface" I would find that my address is
actually 2001:192:10:1::2 which (IMHO) makes it much easier to remember, and
to test out!
If you had specific needs on the lab, they would tell you their opinion. If
they do not, it's all fair, so do what you want. I recommend setting your
own just so you have to type less! I'm not sure what the MTBF on typing
fingers is, but I don't want to waste anything on IPv6! (grin)

Subject: IPv6 Addressing
Hi All,
I am using InternetworkExpert 4.0 guide and I see that there is no a
standardization to make IPv6 addressing. Assume that we have been forced to
use a 64-bit subnet ( 2001:192:10:1::/64) on addressing. On the some tasks
solution guide has used the all host portion of global and link-local IPv6
address (ex. 2001:192:10:1:204:27FF:FEB5:2F60) when it identifies the frame
relay mapping entries for Frame Relay connections but on the some tasks the
solutions includes the router identifier (ex. 2001:192:10:1:204::2) as host
portion address rather than using all host portion.
Please tell me the standardization to be used on the exam.
Regards,
Engin KARTAL
