considered as works in progress. Please refer to the IETF Web site at http://www.ietf.org
for the latest drafts.
Before You Begin
You can configure PIM on IPv4 and IPv6 interfaces. However, IPv6 does not support all
PIM configuration options. For information about configuring PIM on IPv6 interfaces, see
“Configuring PIM for IPv6 Multicast” on page 207.
Enabling PIM on a VR
By default, PIM is disabled. To enable PIM on a VR:
1. Enable multicast routing. (See “Enabling IP Multicast” on page 6.)
2. Create a VR, or access an existing VR context.
host1(config)#virtual-router boston
3. Create and enable PIM processing.
host1:boston(config)#router pim
router pim
• Use to create and enable PIM processing on a VR or to access Router Configuration
mode.
• Example
host1:boston(config)#router pim
• Use the no version to remove PIM from the VR.
• See router pim.
Disabling PIM on a VR
To disable PIM processing on a router, use the pim disable command.
pim disable
• Use to disable PIM processing. By default, PIM processing is enabled.
• Example
host1:boston(config-router)#pim disable
• Use the no version to reenable PIM processing.
• See pim disable.
