Cisco Catalyst 3650 User Manual

•
To participate in IP multicasting, the multicast hosts, routers, and multilayer device must have IGMP
operating.
Restrictions for Configuring IP Multicast Routing
The following are the restrictions for configuring IP multicast routing:
•
IP multicast routing is not supported on devices running the LAN Base feature set.
•
You cannot have a device stack containing a mix of Catalyst 3850 and Catalyst 3650 devices.
Information About IP Multicast Routing
IP multicasting is an efficient way to use network resources, especially for bandwidth-intensive services such
as audio and video. IP multicast routing enables a host (source) to send packets to a group of hosts (receivers)
anywhere within the IP network by using a special form of IP address called the IP multicast group address.
The sending host inserts the multicast group address into the IP destination address field of the packet, and
IP multicast routers and multilayer devices forward incoming IP multicast packets out all interfaces that lead
to members of the multicast group. Any host, regardless of whether it is a member of a group, can send to a
group. However, only the members of a group receive the message.
Cisco’s Implementation of IP Multicast Routing
Cisco IOS software supports the following protocols to implement IP multicast routing:
•
Internet Group Management Protocol (IGMP) is used among hosts on a LAN and the routers (and
multilayer devices) on that LAN to track the multicast groups of which hosts are members.
•
Protocol-Independent Multicast (PIM) protocol is used among routers and multilayer devices to track
which multicast packets to forward to each other and to their directly connected LANs.
The device does not support the Distance Vector Multicast Routing Protocol (DVMRP) nor the Cisco
Group Management Protocol (CGMP).
