# Enabling PIM on a VR

By default, PIM is disabled. To enable PIM on a VR:

1. Enable multicast routing. (See Enabling IP Multicast.)
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.
