IPv4 Multicast Protocols

In this section:

  1. Overview of IP Multicasting
    Multicast protocols allow a group or channel to be accessed over different networks by multiple stations (clients) for the receipt and transmission of multicast data.
  2. Multicast Terms
  3. Support for Multicast Multi-VRF
  4. Changing Global IP Multicast Parameters
  5. Concurrent Support for Multicast Routing and Snooping
  6. Defining the Maximum Number of PIM Cache Entries
    You can define the maximum number of multicast cache entries.
  7. Setting the Maximum Number of IGMP Group Addresses
    You can change the maximum number of IGMP group addresses for the default virtual routing and forwarding (VRF) instance or a specific VRF.
  8. Modifying IGMPv1 and IGMPv2 Parameters
    Various IGMP parameters can be modified from their default values.
  9. Adding an Interface to a Multicast Group
  10. Multicast Non-Stop Routing
    Multicast non-stop routing (NSR) provides hitless-failover support on all platforms for IPv4 multicast features (default and non-default VRFs): PIM-DM, PIM-SM, and PIM-SSM.
  11. Configuring Multicast Non-Stop Routing
    Multicast non-stop routing (NSR) provides hitless-failover support on all platforms for IPv4 multicast features.
  12. Passive Multicast Route Insertion
  13. Viewing PMRI Status and Disabling PMRI
    Passive multicast route insertion (PMRI) is enabled by default. In some situations you may need to view the PMRI status and use the hardware-drop feature to disable PMRI.
  14. IP Multicast Boundaries
  15. Configuration Considerations
  16. Configuring Multicast Boundaries
    An access list is used to define boundaries for PIM enabled interfaces.
  17. Extended ACL to Permit Multicast Traffic
  18. Extended ACL to Deny Multicast Traffic
  19. PIM Dense
  20. PIM Convergence on MAC Address Movement
    PIM convergence occurs when the PIM module is notified of a topology change.
  21. PIM Sparse
  22. IP Multicast PIM Neighbor Filter
    The IP multicast PIM neighbor filter feature allows you to control which devices can be PIM neighbors.
  23. PIM Passive
  24. Multicast Outgoing Interface (OIF) List Optimization
  25. Clearing the PIM Forwarding Cache
  26. Clearing the PIM Message Counters
  27. Configuring Multicast Source Discovery Protocol
  28. Configuring MSDP Mesh Groups
  29. MSDP Anycast RP
  30. PIM Anycast RP
  31. Displaying PIM Information
    You can use various show commands to view information about PIM.
  32. Static Multicast Routes
    Configure static multicast routes to control the network paths, administrative distance, and precedence for multicast routes.
  33. IGMP Proxy
  34. IGMPv3
