Hello,
I don't understand why "2001:a:a:2::3" would not be a valid address, it is not taken by any of the other hosts in the network from what I can see.
Thanks for the help!
Hello,
Inside the network the subnet mask is 80, therefore if you choose
"2001:a:a:a:2::3" (and not "2001:a:a:2:3" otherwise you don't
satisfies the delegated prefix), B will be in the same subnetwork
(2001:a:a:a:2/80) as R2-south, what is not possible.
There is also a typo in the correction, a "000a" is missing, the correct phrase is:
"Since the subnet mask is 80 bits, the subnet prefix should be precisely 2001:000a:000a:000a:000x::/80 with x∈ {0, 1, 2, ...f }". I will update that on Moodle.
Best,
Stéphan.
