Protocol Independent Multicast (PIM)
Protocol Independent Multicast-Sparse Mode (PIM-SM) supports multicast groups spread out across large areas of a company or the Internet. For more information about PIM-SM concepts and terminology, refer to Configuring IP Multicast Routing Protocols.
The 8000 Series switches support the following for PIM-SM:
- RP functionality
- Redundant RP configuration where several RPs can be configured for the same group(s)
- RP load sharing where several RPs can be configured in the same PIM domain
- BSR functionality
- Redundant BSR functionality
- MBR functionality to connect a PIM-SM domain to a DVMRP domain. When you configure an 8000 Series switch with MBR functionality, you can have some interfaces running PIM-SM and other interfaces running DVMRP to interconnect a PIM-SM domain to a DVMRP domain.
