for assistance.
Use the pool ipv6 command to enter IPv6 pool configuration submode.
Multiple prefix-ranges are allowed within a pool. The length of the prefix in any pool is the same for all
prefix's and this is imposed by the prefix-length command. The prefix-length has to be mandatorily configured
whenever prefix-range is configured.
