PIM Sparse

Brocade devices support Protocol Independent Multicast (PIM) Sparse version 2. PIM Sparse provides multicasting that is especially suitable for widely distributed multicast environments. The Brocade implementation is based on RFC 2362.

In a PIM Sparse network, a PIM Sparse device that is connected to a host that wants to receive information for a multicast group must explicitly send a join request on behalf of the receiver (host).

PIM Sparse devices are organized into domains. A PIM Sparse domain is a contiguous set of devices that all implement PIM and are configured to operate within a common boundary. Figure 5 shows a simple example of a PIM Sparse domain. This example shows three devices configured as PIM Sparse devices. The configuration is described in detail following the figure.

Devices that are configured with PIM Sparse interfaces also can be configured to fill one or more of the following roles:
