IPv6 DHCP Snooping VLAN Configuration

Use the IPv6 DHCP Snooping VLAN Configuration page to view and configure the IPv6 DHCP (Dynamic Host Configuration Protocol) snooping settings on VLANs that exist on the device. IPv6 DHCP snooping can be configured on switching VLANs and routing VLANs. For Layer 2 (non-routing) VLANs, IPv6 DHCP snooping forwards valid DHCPv6 client messages received on the VLANs. The message is forwarded on all trusted interfaces in the VLAN. When a DHCPv6 packet is received on a routing VLAN, the IPv6 DHCP snooping application applies its filtering rules and updates the bindings database. If a client message passes filtering rules, the message is placed into the software forwarding path, where it may be processed by the DHCPv6 relay agent, processed by the local DHCPv6 server, or forwarded as an IP packet.
