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.
