Hello Guys,
Apologies if so many of you find this appalling, I have searched through
GS archives and have gone through so many posts on this topic.
Unfortunately, I still don't get it straight. I know that I don't have
to get 100% to pass my CCIE in 12 days time, but I am genuinely aspiring
for 120% to be honest.
IPv6 is the only topic that I still don't have a good grasp with; I've
read DocCD on IPv6 and personally found this to be the most
insufficient. I have even gone as far as looking through the RFCs
documentations and all stuff, but I see GS as my last resort in
understanding the "Behind the doors" principles with this IPv6.
Knows:-
I know what IPv6 is all about and why we have them.
I know the difference between IPv6 and IPv4 and "How" to configure them
I know IPv6 is 128bits, first 64bits representing network and the last
64bits representing hosts
I know the theoretical difference between Site-Link, Link-Local and
Global Addresses
I know theoretically that you'll have to map remote link-local Addresses
to respective frame-relay pvc only when you're using Dynamic Routing
Protocol within the IPv6 domain.
Don't knows:-
1. When would I need to configure Global Addresses and when to
configure Site-Link/Link-Local Addresses?
- Will this be based on what's given in the question
2. What is the difference between configuring something like
2001:CC1E:1234::/64 on an interface, and something like
2001:CC1E:1234::1/64
- What's the technical difference between this one, since I can
manually configure link-local FE80::1/64 to influence the host portion
for 2001:CC1E:1234::/64
3. When would I need to use just static route to get to remote
link-local/global addresses and when to just use frame-relay map ipv6
<addr> <dlci> [b] command for local-link addresses.
- Will this be based on what's given in the question with
regards to using ipv6 static route or dynamic protocol
- Is the reason for 3. because routers don't forward link-local
address by default?
Once again, I apologise if this happen to disturb anyone considering the
fact that there are some posts within the archives and my Lab is in 12
days time, I just don't want to memorise configuration steps, my
preparation as be centred around understanding the principles behind
things. In this case, DocCD has been inadequate for me.
So many people have mentioned the IPv6 seminar delivered by IE and
IPExpert, I've searched everywhere on their websites but couldn't find
IPv6 seminar in their archives. Please if any of you have the free
archived seminar by IE/IPExpert, let me know ... Don't know if IPv6 can
take up to 8 points in the exam, but this can make a difference as
you'll agree with me.
Many Thanks
