Supported PIM Modes and Features

© Copyright Lenovo 2016
For each interface attached to a PIM network component, PIM can be configured to
operate either in PIM Sparse Mode (PIM‐SM) or PIM Dense Mode (PIM‐DM).
 PIM‐SM is used in networks where multicast senders and receivers comprise a
relatively small (sparse) portion of the overall network. PIM‐SM uses a more
complex process than PIM‐DM for collecting and optimizing multicast routes,
but minimizes impact on other IP services and is more commonly used.
PIM‐DM is used where multicast devices are a relatively large (dense) portion of

the network, with very frequent (or constant) multicast traffic. PIM‐DM requires
less configuration on the switch than PIM‐SM, but uses broadcasts that can
consume more bandwidth in establishing and optimizing routes.
The following PIM modes and features are not currently supported in ENOS 8.4:
 Hybrid Sparse‐Dense Mode (PIM‐SM/DM). Sparse Mode and Dense Mode may
be configured on separate IP interfaces on the switch, but are not currently
supported simultaneously on the same IP interface.
 PIM Source‐Specific Multicast (PIM‐SSM)
Anycast RP

 PIM RP filters
Only configuration via the switch ISCLI is supported. PIM configuration is

currently not available using the menu‐based CLI, the BBI, or via SNMP.
