•
Enable DHCPv6 snooping on the device to record the IPv6 address and the MAC address of
the host in a DHCPv6 snooping entry.
•
Enable dynamic IPv6SG on GigabitEthernet 2/0/1 to filter received packets based on DHCPv6
snooping entries. Only packets from the client that obtains an IP address from the DHCPv6
server are allowed to pass.

Configuration procedure
1. Configure DHCPv6 snooping:
# Enable DHCPv6 snooping globally.
<Device> system-view
[Device] ipv6 dhcp snooping enable
# Configure GigabitEthernet 2/0/2 as a trusted interface.
[Device] interface gigabitethernet 2/0/2
[Device-GigabitEthernet2/0/2] ipv6 dhcp snooping trust
[Device-GigabitEthernet2/0/2] quit
2. Enable IPv6SG:
# Enable IPv6SG on GigabitEthernet 2/0/1 and verify the source IP address and MAC address
for dynamic IPv6SG.
[Device] interface gigabitethernet 2/0/1
[Device-GigabitEthernet2/0/1] ipv6 verify source ip-address mac-address
# Enable recording of client information in DHCPv6 snooping entries on GigabitEthernet 2/0/1.
[Device-GigabitEthernet2/0/1] ipv6 dhcp snooping binding record
[Device-GigabitEthernet2/0/1] quit
Verifying the configuration
# Verify that a dynamic IPv6SG binding is generated based on a DHCPv6 snooping entry.
[Device] display ipv6 source binding dhcpv6-snooping
