What Multicast Protocols Does the Switch Support?

Multicast protocols are used to deliver Multicast packets from one source to

multiple receivers. Table 42-1 summarizes the multicast protocols that the

switch supports.

Table 42-1. Multicast Protocol Support Summary

Hosts must have a way to identify their interest in joining any particular

multicast group, and routers must have a way to collect and maintain group

memberships. These functions are handled by the IGMP protocol in IPv4. In

IPv6, multicast routers use the Multicast Listener Discover (MLD) protocol

to maintain group membership information.

Multicast routers must also be able to construct a multicast distribution tree

that enables forwarding multicast datagrams only on the links that are

required to reach a destination group member. Protocols such as DVMRP, and

PIM handle this function.

IGMP and MLD are multicast group discovery protocols that are used

between the clients and the local multicast router. PIM-SM, PIM-DM, and

DVMRP are multicast routing protocols that are used across different

subnets, usually between the local multicast router and remote multicast
