62.3 SAVI Typical Application
In actual application, SAVI function is usually applied in access layer switch to check the validity of node
source address on direct-link. There are four typical application scenes for SAVI function: DHCP-Only,
Slaac-Only, DHCP-Slaac and Static binding. In network environment, users can select the corresponding
scene according to the actual requirement; in double stacks network, while SAVI function associates with IPv4
DHCP snooping to use, IPv4 and IPv6 source address authentication is implemented.
Typical network topology application for SAVI function:
Client_1
Client_2
Ethernet1/0/13Ethernet1/0/12
Switch2 Switch1
Ethernet1/0/1 Ethernet1/0/2
Switch3
Client_1 and Client_2 means two different user’s PC installed IPv6 protocol, respectively connect with port
