Example for Configuring a DHCPv6 Client
Networking Requirements
In Figure 9-20, the RouterIndustrial Switch Router is required to function as a DHCPv6 client and obtain an IPv6 address and other configuration parameters from the DHCPv6 server. The address of the DHCPv6 server is fc00:3::1/64. The DHCPv6 server and client are on the same link.
Configuration Roadmap
The configuration roadmap is as follows:
Enable IPv6 functions on the interface so that devices can communicate using IPv6.
Enable the DHCPv6 client function so that devices can obtain IPv6 addresses using DHCPv6.
Procedure
- Configure IPv6 functions on an interface.
<Huawei> system-view [Huawei] sysname Router A [Router A] ipv6 [Router A] interface gigabitethernet 0/0/1 [Router A-GigabitEthernet0/0/1] ipv6 enable [Router A-GigabitEthernet0/0/1] ipv6 address auto link-local [Router A-GigabitEthernet0/0/1] ipv6 address auto global default
- Enable the DHCPv6 client function.
# Enable the DHCPv6 client function on GE 0/0/1.
[Router A-GigabitEthernet0/0/1] ipv6 address auto dhcp
- Verify the configuration.
# Run the display dhcpv6 client command on the Router A to check the DHCPv6 client configurations.
