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. Layer 3 IPv4 Multicast Scaling Numbers
    The Layer 3 IPv4 Multicast Scaling Numbers for RUCKUS devices are shown in the following table.
  3. Multicast Terms
  4. Support for Multicast Multi-VRF
  5. Changing Global IP Multicast Parameters
  6. Concurrent Support for Multicast Routing and Snooping
  7. Defining the Maximum Number of PIM Cache Entries
    You can define the maximum number of multicast cache entries.
  8. 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, globally or at the interface level.
  9. Configuring the IGMP Report Filter Policy
    The IGMP report filter policy can be configured globally, for a non-default VRF instance, or for an interface. The following task configures the IGMP report filter policy globally.
  10. IPv4 PIM Register Message Rate Limit
    When a new source begins transmitting within a Protocol Independent Multicast (PIM) network, the designated router (DR) encapsulates multicast packets into register messages and forwards them to the rendezvous point (RP). If the source is running at a high data rate with many new sources starting concurrently, pressure can be put on the CPU due to the large number of multicast packet streams being sent to the network. This situation can occur after a network or power failure. To avoid this scenario, the rate limit for the number of register messages should be set to a relatively low value. This value is based on the known number of multicast sources present.
  11. IPv4 PIM Register Message Filter Rule
    Protocol Independent Multicast (PIM) register messages received from a downstream multicast designated router (DR) should be filtered for reserved or any other undesirable multicast groups.
  12. Modifying IGMPv1 and IGMPv2 Parameters
    Various IGMP parameters can be modified from their default values.
  13. Adding an Interface to a Multicast Group
  14. 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.
  15. Configuring Multicast Non-Stop Routing
    Multicast non-stop routing (NSR) provides hitless-failover support on all platforms for IPv4 multicast features.
  16. Passive Multicast Route Insertion
  17. 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.
  18. IP Multicast Boundaries
  19. Configuration Considerations
  20. Configuring Multicast Boundaries
    An access list is used to define boundaries for PIM enabled interfaces.
  21. Extended ACL to Permit Multicast Traffic
  22. Extended ACL to Deny Multicast Traffic
  23. PIM Dense
  24. PIM Convergence on MAC Address Movement
    PIM convergence occurs when the PIM module is notified of a topology change.
  25. PIM Sparse
  26. IP Multicast PIM Neighbor Filter
    The IP multicast PIM neighbor filter feature allows you to control which devices can be PIM neighbors.
  27. PIM Passive
  28. Multicast Outgoing Interface (OIF) List Optimization
  29. Clearing the PIM Forwarding Cache
  30. Clearing the PIM Message Counters
  31. Configuring Multicast Source Discovery Protocol
  32. Configuring MSDP Mesh Groups
  33. MSDP Anycast RP
  34. PIM Anycast RP
  35. IPv4 PIM Join and Prune Policy
    The IPv4 PIM Join and Prune Policy provides the capability for the following options to be configured:.
  36. Displaying PIM Information
    You can use various show commands to view information about PIM.
  37. Static Multicast Routes
    Configure static multicast routes to control the network paths, administrative distance, and precedence for multicast routes.
  38. IGMP Proxy
  39. IGMPv3
