Globally Enabling or Disabling the PIM Feature

Defining a PIM Network Component

Defining an IP Interface for PIM Use

By default, PIM is disabled on the switch. PIM can be globally enabled or disabled
using the following ISCLI commands:
CN4093(config)# [no] ip pim enable
The CN4093 can be attached to a maximum of two independent PIM network
components. Each component represents a different PIM network, and can be
defined for either PIM‐SM or PIM‐DM operation. Basic PIM component
configuration is performed using the following commands:
CN4093(config)# ip pim component <1‐2>
CN4093(config­ip­pim­comp)# mode {sparse|dense}
CN4093(config­ip­pim­comp)# exit
The sparse option will place the component in Sparse Mode (PIM‐SM). The
dense option will place the component in Dense Mode (PIM‐DM). By default, PIM
component 1 is configured for Sparse Mode. PIM component 2 is unconfigured by
default.
Note: A component using PIM-SM must also be configured with a dynamic or static
Rendezvous Point (see
Each network attached to an IP interface on the switch may be assigned one of the
available PIM components. The same PIM component can be assigned to multiple
IP interfaces. The interfaces may belong to the same VLAN, but each interface can
belong to only one VLAN.
To define an IP interface for use with PIM, first configured the interface with an
IPv4 address and VLAN as follows:
CN4093(config)# interface ip <Interface number>
CN4093(config­ip­if)# ip address <IPv4 address> <IPv4 mask>
CN4093(config­ip­if)# vlan <VLAN number>
CN4093(config­ip­if)# enable
Note: The PIM feature currently supports only one VLAN for each IP interface.
Configurations where different interfaces on different VLANs share IP addresses
are not supported.
Next, PIM must be enabled on the interface, and the PIM network component ID
must be specified:
CN4093(config­ip­if)# ip pim enable
CN4093(config­ip­if)# ip pim component­id <1‐2>
CN4093(config­ip­if)# exit
By default, PIM component 1 is automatically assigned when PIM is enabled on
the IP interface.
Note: While PIM is enabled on the interface, the interface VLAN cannot be
changed. To change the VLAN, first disable PIM on the interface.
