Multicast overview

Multicast allows high-efficiency point-to-multipoint data transmission over a network. Layer 2 multicast is not supported. Multicast involves these topics:

l      Multicast model classification

l      Multicast architecture

l      Multicast packet forwarding mechanism

Multicast routing and forwarding

Multicast policies are used for filtering the routing information used in the RPF check.

l      Multicast policy overview

l      Configuring a multicast policy

IGMP

The Internet Group Management Protocol (IGMP) is the protocol responsible for IP multicast group member management in the TCP/IP protocol stack. Perform the following tasks to configure IGMP:

l      Configuring basic functions of IGMP

l      Adjusting IGMP performance

MSDP

The Multicast source discovery protocol (MSDP) is an inter-domain multicast solution developed to address the interconnection of protocol independent multicast sparse mode (PIM-SM) domains. Perform the following tasks to configure MSDP:

l      Configuring basic functions of MSDP

l      Configuring MSDP peer parameters

l      Configure SA messages related parameters

PIM

Protocol Independent Multicast (PIM) provides IP multicast routing by leveraging static routes or unicast routing tables generated by any unicast routing protocol. Perform the following tasks to configure PIM:

l      Configuring PIM-DM

l      Configuring PIM-SM

l      Configuring PIM-SSM

l      Configuring PIM common features
