RADVD and enable the MLD snooping function.
Figure 65. WMI: IPv6 Auto Configuration
• Enable DHCPv6 Server: WIDE-DHCPv6 is an open-source implementation of dynamic host configura-
tion protocol for IPv6 (DHCPv6) originally developed by the KAME project. The implementation mainly
complies with the following standards: RFC3315, RFC3319, RFC3633, RFC3646, RFC4075, RFC 4272
etc.
• Enable RADVD: The router advertisement daemon (RADVD) is run by Linux or BSD systems acting as
IPv6 routers. It sends router advertisement messages, specified by FC2461, to a local Ethernet LAN period-
ically and when requested by a node sending a router solicitation message. These messages are required for
IPv6 stateless auto-configuration.
• Enable MLD Snooping: Multicast Listener Discovery Snooping (MLD Snooping) is an IPv6 multicast
constraining mechanism that runs on Layer 2 devices to manage and control IPv6 multicast groups. By ana-
