DHCPv6 snooping configuration example

Network requirements

As shown in
GigabitEthernet 1/0/1, to the unauthorized DHCPv6 server through GigabitEthernet 1/0/3, and to the
DHCPv6 client through GigabitEthernet 1/0/2.
Configure only the port connected to the authorized DHCPv6 server to forward the responses from
the DHCPv6 server. Enable the DHCPv6 snooping device to record DHCPv6 snooping address
entries.
