Chapter 8 Home Networking Table 30 Network Setting > Home Networking > LAN Setup (continued) LABEL MLD Snooping MLD Mode DESCRIPTION Multicast Listener Discovery (MLD) allows an IPv6 switch or router to discover the presence of MLD hosts who wish to receive multicast packets and the IP addresses of multicast groups the hosts want to join on its network. Select Enable MLD Snooping to activate MLD Snooping on the Device. This allows the Device to check MLD packets passing through it and learn the multicast group membership. It helps reduce multicast traffic. Select Standard Mode to have the Device forward IPv6 multicast packets to a port that joins the IPv6 multicast group and broadcast unknown IPv6 multicast packets from the WAN to all LAN ports. Select Blocking Mode to have the Device block all unknown IPv6 multicast packets from the WAN. LAN IPv6 Address Assign Setup Select how you want to obtain an IPv6 address: • Stateless: The Device uses IPv6 stateless autoconfiguration. RADVD (Router Advertisement Daemon) is enabled to have the Device send IPv6 prefix information in router advertisements periodically and in response to router solicitations. DHCPv6 server is disabled. • Stateful: The Device uses IPv6 stateful autoconfiguration. The DHCPv6 server is enabled to have the Device act as a DHCPv6 server and pass IPv6 addresses to DHCPv6 clients. • Stateless and Stateful: The Device uses both IPv6 stateless and stateful autoconfiguration. The LAN IPv6 clients can obtain IPv6 addresses either through router advertisements or through DHCPv6. LAN IPv6 DNS Assign Setup Select how the Device provide DNS server and domain name information to the clients: • From Router Advertisement: The Device provides DNS information through router advertisements. • From DHCPv6 Server: The Device provides DNS information through DHCPv6. • From RA & DHCPv6 Server: The Device provides DNS information through both router advertisements and DHCPv6. DHCPv6 Configuration DHCPv6 State This shows the status of the DHCPv6. IPv6 Router Advertisement State RADVD State This shows whether RADVD is enabled or not. IPv6 DNS Values IPv6 DNS Server 1-3 Select From ISP if your ISP dynamically assigns IPv6 DNS server information. Select User-Defined if you have the IPv6 address of a DNS server. Enter the DNS server IPv6 addresses the Device passes to the DHCP clients. DNS Query Scenario Apply Cancel Select None if you do not want to configure IPv6 DNS servers. Select how the Device handles clients' DNS information requests. • IPv4/IPv6 DNS Server: The Device forwards the requests to both the IPv4 and IPv6 DNS servers and sends clients the first DNS information it receives. • IPv6 DNS Server Only: The Device forwards the requests to the IPv6 DNS server and sends clients the DNS information it receives. • IPv4 DNS Server Only: The Device forwards the requests to the IPv4 DNS server and sends clients the DNS information it receives. • IPv6 DNS Server First: The Device forwards the requests to the IPv6 DNS server first and then the IPv4 DNS server. Then it sends clients the first DNS information it receives. • IPv4 DNS Server First: The Device forwards the requests to the IPv4 DNS server first and then the IPv6 DNS server. Then it sends clients the first DNS information it receives. Click Apply to save your changes. Click Cancel to restore your previously saved settings. VMG1312-B Series User's Guide 130
