• Entering a no router pim command removes all configuration for PIM multicast on a Layer 3
Switch (router pim level) only.
Globally Enabling and Disabling PIM without Deleting Multicast Configuration
As stated above entering a no router pim command deletes the PIM configuration. If you want to
disable PIM without deleting any PIM configuration, enter the following command.
PowerConnect(config)#router pim
PowerConnect(config-pim-router)#disable-pim
Syntax: [no] disable-pim
Use the [no] version of the command to re-enable PIM.
Enabling a PIM version
Using the CLI
To enable PIM on an interface, globally enable PIM, then enable PIM on interface 3, enter the
following commands.
PowerConnect(config)#router pim
PowerConnect(config)#int e 3
PowerConnect(config-if-e1000-3)#ip address 207.95.5.1/24
PowerConnect(config-if-e1000-3)#ip pim
Syntax: [no] ip pim [version 1 | 2]
The version 1 | 2 parameter specifies the PIM DM version. The default version is 2.
If you have enabled PIM version 1 but need to enable version 2 instead, enter either of the
following commands at the configuration level for the interface.
PowerConnect(config-if-1/1)#ip pim version 2
PowerConnect(config-if-1/1)#no ip pim version 1
To disable PIM DM on the interface, enter the following command.
PowerConnect(config-if-1/1)#no ip pim
Modifying PIM global parameters
PIM global parameters come with preset values. The defaults work well in most networks, but you
can modify the following parameters if you need to:
• Neighbor timeout
• Hello timer
• Prune timer
• Prune wait timer
• Graft retransmit timer
• Inactivity timer
Modifying neighbor timeout
Neighbor timeout is the interval after which a PIM router will consider a neighbor to be absent.
Absence of PIM hello messages from a neighboring router indicates that a neighbor is not present.
The default value is 180 seconds.
