IPv6 Pool

Hey,

Routerboard 1100ahx2
RouterOS: 5.18

I have defined the IPv6 prefix that was assigned to me as an IPv6 pool

Prefix: 2axx:xxx0:2ef::/48
Prefix Lenght: /62

A PPPoE Server uses this pool to give the /62 prefixes to the users. Actually this is working nice, but I was informed by some customers that the IPv6 is not working. I found that these useres were given subnets that are not part of me above given /48 prefix.
e.g.:
2axx:xxx0:6ff:12e8::/62

As far as I understood, the defined pool should only include prefixes beginning with
2axx:xxx0:2ef ???

How can that be?

could you generate support output file and send it to support@mikrotik.com
