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.
Active
Select
Enable
to activate MLD Snooping on the VMG3925-B10A. This allows the VMG3925-B10A
to check MLD packets passing through it and learn the multicast group membership. It helps
reduce multicast traffic.
MLD Mode
Select

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.
LAN IPv6 DNS
Assign Setup
Select how the VMG provide DNS server and domain name information to the clients:
