Cheers Scott,
Your response on issue 2 is helpful; to be honest, just got to know that
.0 is a valid address in ipv6 world. I understand the issue with eui-64,
how it works and I also comprehend your comment about point 1. So I'm
left with issue 3 now.
An excerpt from your reply:
"3. Same rules as IPv4. If you are on the same subnet, you'll want to
have Layer3 to Layer2 mapping (otherwise you'd get "encapsulation
failed" messages in "debug ipv6 packet") just like in Ipv4! The
difference here is that you have multiple addresses to use!"
... But we don't usually do remote addresses' layer3 to layer2 mapping
in IPv4. I thought Routing takes care of that (either static/dynamic).
Using Static Route within IPv6 domain usually don't need Layer3 to
Layer2, But for dynamic routing, you certainly do. I certainly
understand the concept of Layer3-2-Layer2 mapping else I wouldn't see
myself prepared for this exam by now, what I'm struggling with is why do
this(L3-to-L2 mapping) for remote addresses when using Dynamic RPs
within IPv6 domain.
Many Thanks
