IGMP
IGMP, known as
Internet Group Management Protocol
, is used to management hosts from multicast
group.
IGMP Proxy: Enables or disables the router’s IGMP Proxy.
Upstream Interface: When IGMP Proxy enabled, sets one of the router’s existing IP interfaces as the
upstream interface; all other router interfaces are designated downstream interfaces.
IGMP Forward All: Enables/Disables your router’s ability to forward multicast traffic to ALL interfaces.
IGMP Snooping: Enables/Disables the IGMP Snoop functionality in the bridge. When the IGMP snoop
functionality is enabled, all the attached bridge interfaces are designated as downstream interfaces.
MLD
MLD, short for Multicast Listener Discovery protocol, is a component if the Internet Protocol version
6(IPv6) suite. MLD is used by IPv6 to discover multicast listeners on a directly attached link, much as
IGMP used in IPv4. The protocol is embedded in ICMPv6 instead of using a separate protocol. MLDv1 is
similar to IGMPv2 and MLDv2 is similar to IGMPv3.
MLD Proxy:
check whether to enable this function. MLD ( Multicast Listener Discovery Protocol) Proxy
intercepts the MLD request from Clients and forwards it to the router after some dealings. Support MLDv1
and MLDv2.
Upstream Interface:
When MLD Proxy enabled, sets one of the router’s existing IP interfaces as the
upstream interface; all other router interfaces are designated downstream interfaces.
MLD Forward All:
select enable to forward the multicast packets to all ports. If select disable, the
multicast packets will be forwarded to ports set according to the MLD Snooping below.
MLD Snooping: similar to IGMP snooping, listens in on the MLD conversation between hosts and
