The protocol is named Protocol Independent Multicast - Dense Mode (PIM-DM) overview PIM relies on the unicast routing tables to identify the path back to a multicast source. Along the way, we introduce some important concepts regarding multicast on Cisco IOS-XE routers and PIM. A Palo Alto Networks® firewall supports PIM Sparse Mode (PIM-SM) (RFC 4601), PIM Any-Source Multicast (ASM) (sometimes referred to as PIM Sparse Mode), and PIM Source-Specific Multicast (SSM). PIM-SM uses shared trees by This document obsoletes RFC 4601 by replacing it, addresses the errata filed against it, removes the optional (*,*,RP), PIM Multicast Border Router features and authentication using IPsec that RFC 5186 IGMPv3/MLDv2 and Multicast Protocols May 2008 4. · RFC 3973, Protocol Independent Multicast-Dense Mode (PIM-DM): Protocol Specification (Revised) · RFC 4601, Protocol Independent Multicast-Sparse Mode (PIM-SM): Protocol Specification (Revised) PIM Dense Mode (PIM-DM) is the brute-force approach to delivering multicast.
