Method used to obtain DNS and NetBIOS information through the public network

Huawei AR series routers can automatically assign the DNS server IP address allocated by a carrier, DNS domain name suffix, and NetBIOS server address to a DHCP client. The configuration procedure is as follows.
-Interface address pool
[Huawei] interface gigabitethernet 1/0/0
[Huawei-GigabitEthernet1/0/0] dhcp select interface
[Huawei-GigabitEthernet1/0/0] dhcp server import all //Enable the interface to automatically obtain the DNS and NetBIOS server addresses.
-Global address pool
[Huawei] ip pool global
[Huawei-ip-pool-global] import all //Enable the AR to automatically obtain the DNS and NetBIOS server addresses in the global address pool.
