Configuration procedure
# Configure the IPv6 source guard feature on Ethernet 1/0/1 to filter packets based on both the source
IP address and MAC address.

Dynamic IPv6 source guard using DHCPv6 snooping
configuration example
Network requirements
As shown in Figure 113 , enable DHCPv6 and DHCPv6 snooping on the device. The host can obtain an
IP address through the DHCPv6 server and the IPv6 IP address and the MAC address of the host can be
recorded in a DHCPv6 snooping entry.
Enable IPv6 source guard feature on the device's port Ethernet 1/0/1 to filter packets based on DHCPv6
snooping entries, allowing only packets from a client that obtains an IP address through the DHCP server
to pass.
