IPv6 address acquisition configuration example
Network requirements
As shown in Figure 77, configure the switch to use DHCPv6 to obtain configuration parameters from the DHCPv6 server. The parameters include IPv6 address, DNS server address, domain name suffix, SIP server address, and SIP server domain name.
Figure 77: Network diagram
Configuration procedure
You must configure the DHCPv6 server first before configuring the DHCPv6 client. For information about configuring DHCPv6 server, see "Configuring the DHCPv6 server."
# Configure VLAN-interface 2 as a DHCPv6 client for IPv6 address acquisition. Configure the DHCPv6 client to support DHCPv6 rapid address assignment. Configure the DHCPv6 client to create a dynamic DHCPv6 option group for saving configuration parameters.

Verifying the configuration
# Verify that the client has obtained an IPv6 address and other configuration parameters from the server.
