Static Multicast

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:
