What is the difference between IGMP and PIM?
Important is the Note: To use PIM snooping, you must enable IGMP snooping on the switch. IGMP snooping restricts multicast traffic that exits through the LAN ports to which hosts are connected. IGMP snooping does not restrict traffic that exits through the LAN ports to which one or more multicast routers are connected.
What is SPT in PIM?
IP Multicast. PIM. Shortest-Path Tree (SPT) and Shared Tree.
Which multicast group is used for all PIM router?
All PIM protocols share a common control message format. PIM control messages are sent as raw IP datagrams (protocol number 103), either multicast to the link-local ALL PIM ROUTERS multicast group, or unicast to a specific destination.
What is RPT in multicast?
The RPT is the path between the RP and receivers (hosts) in a multicast group (see Figure 1). The RPT is built by means of a PIM join message from a receiver’s DR: A receiver sends a request to join group (G) in an Internet Group Management Protocol (IGMP) host membership report.
How to configure Protocol Independent Multicast ( PIM )?
Table 1. Default Multicast Routing Configuration Feature Default Setting Multicast routing Disabled on all interfaces. PIM version Version 2. PIM mode No mode is defined. PIM stub routing None configured.
Is the Pim protocol dependent on unicast routing?
PIM is not dependent on a specific unicast routing protocol; it is IP routing protocol independent and can leverage whichever unicast routing protocols are used to populate the unicast routing table, including Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), and static routes.
Which is multicast routing protocol do you use?
Multicast routing protocols build a loop-free distribution tree of routers that connect the multicast sources and receivers. In this experiment, we will use the Protocol-Independent Multicast (PIM) protocol. (Here, “protocol-independent” means that you can use it together with any unicast routing protocol.)
What is PIM Sparse Mode ( PIM-SM )?
PIM Sparse Mode (PIM-SM) is a multicast routing protocol designed on the assumption that recipients for any particular multicast group will be sparsely distributed throughout the network. In other words, it is assumed that most subnets in the network will not want any given multicast packet.
