CHAPTER 21

Protocol Independent Multicast

BLADEOS supports Protocol Independent Multicast (PIM) in Sparse Mode (PIM-SM) and Dense Mode (PIM-DM).

Note – BLADEOS 6.5 does not support IPv6 for PIM.

The following sections discuss PIM support for the RackSwitch G8124:

PIM Overview

PIM is designed for efficiently routing multicast traffic across one or more IPv4 domains. This has benefits for application such as IP television, collaboration, education, and software delivery, where a single source must deliver content (a multicast) to a group of receivers that span both wide-area and inter-domain networks.

Instead of sending a separate copy of content to each receiver, a multicast derives efficiency by sending only a single copy of content toward its intended receivers. This single copy only becomes duplicated when it reaches the target domain that includes multiple receivers, or when it reaches a necessary bifurcation point leading to different receiver domains.

PIM is used by multicast source stations, client receivers, and intermediary routers and switches, to build and maintain efficient multicast routing trees. PIM is protocol independent; It collects routing information using the existing unicast routing functions underlying the IPv4 network, but does not rely on any particular unicast protocol. For PIM to function, a Layer 3 routing protocol (such as BGP, OSPF, RIP, or static routes) must first be configured on the switch.
