Network requirements
Figure 119: Network diagram
As shown in Figure 119, Switch A is the DHCPv6 server. Switch B connects to the DHCPv6 server through interface Ethernet 1/0/1, and connects to two DHCPv6 clients through interfaces Ethernet 1/0/2 and Ethernet 1/0/3. The three interfaces of Switch B belong to VLAN 2. The client can obtain IP address only through DHCPv6. Configure SAVI on Switch B to automatically bind the IP addresses assigned through DHCPv6 and permit only packets from bound addresses and link-local addresses.
