Congratulations on completing another skill.
Now, it's time for a review in the form of a quiz.
As we go through these questions,
be sure to pause the video after each question to give yourself
the opportunity to answer the question yourself
before we then go over the answer.
That said, let's jump in with our first question.
What address family is used in MPLS 6VPE
to exchange the IPv6 prefixes between the PE routers?
So for this answer, let's just go down our list here.
Number 1 is v6vpn.
Not even really sure what that's supposed to be.
That's definitely an incorrect answer.
There is no v6vpn.
Same with number 2.
L3v6.
That's not anything either.
These are just made-up answers.
Number 3 is ipv6 unicast.
Now, we could make a certain argument
that that might be correct if we were talking about 6PE,
but this is 6VPE, which means, this is our VPN solution, which
means that 3 would be an incorrect answer,
and at the same time, would mean that 4 is a correct answer.
It's going to use vpnv6.
Once again, labeled unicast is a tag that would go along
with 6PE but not 6VPE.
So that makes our correct answer.
Number 4, vpnv6.
Next question.
With a 6to4 tunnel, if the local tunnel endpoint
has an IPv6 address of 156.45.66.37,
what will the local site IPv6 prefix be?
So of course, one of our key factors here,
we are talking about a 6to4 tunnel.
And by definition, a 6to4 tunnel will always start 2002.
So that part is a given.
Then, of course, what we need to do
is we need to convert each part of our IPv4 address into hex.
So the 156 becomes the 9c.
The 45 becomes the 2d.
66 becomes 42, and 37 becomes the 25.
So this would be the correct IPv6 prefix
for this site, given the IPv4 address and the fact
that it's a 6to4 tunnel.
Final question.
With a 6RD tunnel, if the assigned IPv6 prefix is
2001:db8::/32 and the IPv4 endpoint address is
156.45.66.37, what will the site IPv6 prefix be?
So this, of course, is very similar
to the previous question, except now, it's
6RD tunnel, which, of course, allows
us to use our own prefix rather than the assigned address
that 6-to-4 tunnels have to use.
So what does that mean for our address?
Well, it quite simply means that now, this part of the address
is the part that's going to be given
because that is our 6RD prefix.
Then we simply take our IPv4 address.
And once again, convert it over to hex.
And this is exactly the same IPv4 address
from the previous question.
So hopefully, you don't have to do the conversion again,
but we should end up with this answer,
which is the 2001:db8:9c2d:4225::/64.
So that would be the correct local site IPv6 prefix.
So that concludes this quiz.
If you find that you are missing any
of the information necessary to answer these questions,
I would encourage you to go back and review
the referenced sources at the bottom of each question.
Otherwise, congratulations on completing Exploring IPv6
Tunnel Options.
I hope this has been informative,
for you and I'd like to thank you for viewing.
