ProSafe M5300 Switch
PIM
The Protocol Independent Multicast protocol is a simple, protocol-independent multicast
routing protocol. PIM uses an existing unicast routing table and a Join/Prune/Graft
mechanism to build a tree. PIM The ProSafe managed switch supports two types of PIM:
sparse mode (PIM-SM) and dense mode (PIM-DM).
PIM-SM is most effective in networks with a sparse population of multicast receivers. In
contrast, PIM-DM is most effective in networks with densely populated multicast receivers. In
other words, PIM-DM can be used if the majority of network hosts request to receive a
multicast stream, while PIM-SM might be a better choice in networks in which a small
percentage of network hosts, located throughout the network, wish to receive the multicast
stream.
From the PIM-DM link, you can access the following pages:
• PIM Global Configuration on page 304
• SSM Configuration on page 305
• PIM Interface Configuration on page 306
• PIM Neighbor on page 307
• Candidate RP Configuration on page 308

PIM Global Configuration
To display the PIM Global Configuration page, click Routing Multicast PIM Global
Configuration.
To configure global PIM settings:
1. Use PIM Protocol Type to select the PIM type to run:
• PIM-SM. Recommended for networks with sparsely-populated multicast receivers.
• PIM-SM. Recommended for networks with densely-populated multicast receivers.
2. Use Admin Mode to set the administrative status of PIM on the router. The default is
disable.
3. Click APPLY to update the switch with the new settings.
