What is Static Multicast Filter?

Static Multicast Filter allow network administrator to configure multicast group consisting of one or more ranges of MAC multicast addresses. An administrator can control multicast traffic per-switch-port basis with static multicast filter. By default, all multicast traffic are dropped without static multicast filter setup or IGMP snooping which cause some routing protocol such as RIPv2 and OSPF can not be passed through IP DSLAM. So administrator must do any configuration of static multicast filter to pass such routing protocol and other related application smoothly.

Some Well-known multicast group address: 224.0.0.1---------all systems on this subnet
