assigned by DHCPv6 server.
2. With both DHCPv6 and Issue Router Advertisement Enabled
With this method, the PCs' addresses are configured the same like above, and the address
information in RA packets will be neglected.
Start interface ID: Enter the start interface ID. The IPv6 address composed of two parts, thus, the
prefix and the interface ID. Interface is like the Host ID compared to IPv4.
End interface ID: Enter the end interface ID.
Please enter the complete information.
For example: Please enter "0:0:0:2" instead of "::2".
Leased Time (hour): The period of time the IP address assigned will be valid. When expires, the
assigned ID will be recycled and reassigned.
Issue Router Advertisement: Check whether to enable issue Router Advertisement feature. It is to
send Router Advertisement messages periodically.
ULA Prefix Advertisement: Enable this parameter to include the ipv6 ULA address in the RA
messages. ULA, unique local address, is an IPv6 address in the block fc00::/7. It is approximately the
IPv6 counterpart of the IPv4 private address. They are not routable in the global IPv6 Internet.
RADVD Type: The way that ULA prefix is generated.
 Randomly Generated
 Statically Configured: select to set manually in the following parameters.
Prefix: Set the prefix manually.
Preferred Life Time: The ULA prefix life time. When the time is over, the ULA prefix is invalid
any more, -1 means no limit.
Valid Life Time: It is a time threshold, when the time is over, clients should obtain new IPv6
address from the router through RA; -1 means to be limitless.
MLD snooping: Similar to IGMP snooping, listens in on the MLD conversation between hosts and
routers by processing MLD packets sent in a multicast network, and it analyzes all MLD packets
between hosts and the connected multicast routers in the network. Without MLD snooping, multicast
traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports. With MLD
snooping, multicast traffic of a group is only forwarded to ports that have members of that group.
 Standard Mode: In standard mode, multicast traffic will flood to all bridge ports when no
client subscribes to a multicast group.
 Blocking Mode: In blocking mode, the multicast data will be blocked when there is no client
subscribes to a multicast group, it won't flood to the bridge ports.
