When NDRA is used to allocate addresses to the WAN interfaces on a CPE, see Configuring NDRA Address Allocation.
When DHCPv6 (IA_PD) is used to allocate prefixes to a CPE, see Configuring DHCPv6 (IA_PD) Prefix Allocation.
In NDRA+IA_PD address allocation, a DNS server must be configured for both the address pool for NDRA address allocation and the address pool for IA_PD address allocation.
