Chapter 8 Home Networking Table 29 Network Setting > Home Networking > LAN Setup (continued) LABEL DESCRIPTION Static Select this option to configure a fixed IPv6 address for the VMG's LAN IPv6 address. MLD Snooping 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 VMG. This allows the VMG to check MLD packets passing through it and learn the multicast group membership. It helps reduce multicast traffic. LAN IPv6 Address Assign Setup Select how you want to obtain an IPv6 address: • Stateless: The VMG uses IPv6 stateless autoconfiguration. RADVD (Router Advertisement Daemon) is enabled to have the VMG send IPv6 prefix information in router advertisements periodically and in response to router solicitations. DHCPv6 server is disabled. • Stateful: The VMG uses IPv6 stateful autoconfiguration. The DHCPv6 server is enabled to have the VMG act as a DHCPv6 server and pass IPv6 addresses to DHCPv6 clients. • Stateless and Stateful: The VMG 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 VMG provide DNS server and domain name information to the clients: • From Router Advertisement: The VMG provides DNS information through router advertisements. • From DHCPv6 Server: The VMG provides DNS information through DHCPv6. • From RA & DHCPv6 Server: The VMG provides DNS information through both router advertisements and DHCPv6. DHCPv6 Configuration DHCPv6 State This shows the status of the DHCPv6. DHCP Server displays if you configured the VMG to act as a DHCPv6 server which assigns IPv6 addresses and/or DNS information to clients. 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 VMG 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 VMG handles clients' DNS information requests. • IPv4/IPv6 DNS Server: The VMG 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 VMG forwards the requests to the IPv6 DNS server and sends clients the DNS information it receives. • IPv4 DNS Server Only: The VMG forwards the requests to the IPv4 DNS server and sends clients the DNS information it receives. • IPv6 DNS Server First: The VMG 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 VMG 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. VMG3925-B10B User's Guide 118
