Overview
Multicast Filtering
This chapter describes how to configure the following multicast services:
◆
IGMP
– Configures snooping and query parameters.
◆
Filtering and Throttling
maximum of multicast groups allowed on an interface.
◆
MLD Snooping
– Configures snooping and query parameters for IPv6.
◆
Layer 3 IGMP
– Configures IGMP query used with multicast routing.
◆
Multicast VLAN Registration for IPv4
multicast VLAN shared by hosts residing in other standard or private VLAN
groups, preserving security and data isolation.
◆
Multicast VLAN Registration for IPv6
multicast VLAN shared by hosts residing in other standard or private VLAN
groups, preserving security and data isolation.
Multicasting is used to support real-time applications such as video conferencing
or streaming audio. A multicast server does not have to establish a separate
connection with each client. It merely broadcasts its service to the network, and
any hosts that want to receive the multicast register with their local multicast
switch/router. Although this approach reduces the network overhead required by a
multicast server, the broadcast traffic must be carefully pruned at every multicast
switch/router it passes through to ensure that traffic is only passed on to the hosts
which subscribed to this service.
