What is PIM and how does it work?
Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. PIM does not build its own routing tables. PIM uses the unicast routing table for reverse-path forwarding.
How does multicast PIM work?
When a source becomes active, the source DR encapsulates multicast data packets into a PIM register message and sends them by means of unicast to the RP router. When the source DR receives the PIM join message from the receiver’s DR, it starts sending traffic down all SPTs.
What is PIM used for?
PIM (Protocol Independent Multicast) is a multicast routing protocol, that is used to send traffic from a single source to multiple destinations across a network. PIM is a collection of three protocols – PIM Sparse Mode, PIM Dense Mode and PIM Bi-directional .
What PIM means?
Product Information Management
PIM is an acronym for “Product Information Management” and refers, as the name implies, to systems that manage product data. By running processes in parallel, a PIM system helps to improve the time to market of a product significantly, while, at the same time, reducing costs.
What is ip PIM sparse?
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.
What is ip PIM Sparse Mode Cisco?
ip pim sparse-mode command enables your interface (SVI) to participate in sparse mode multicast traffic transmission and multicast shared tree. this way clients in that VLAN are able to receive multicast traffic from different multicast groups (sources) although you can controll it by configuring other parameters.
What is PIM in routing?
Protocol Independent Multicast (PIM) is a collection of multicast routing protocols, each optimized for a different environment. 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 PIM Register tunnel?
When a new PIM RP is configured or learned, a PIM register tunnel interface is created and used for PIM register packets. The interface is deleted when a register-stop packet is received. On the RP, an additional interface is created and used to decapsulate the PIM register packet when it is received.
