Ingress multicast path management policies

Overview

Ingress multicast path management policies are used to manage ingress multicast path bandwidth settings, path decisions, and destination server details that collect and analyze IGMP events associated with residential subscribers. You can create the following ingress multicast path management policy types:

Ingress multicast bandwidth policy

Ingress multicast bandwidth policies are used to manage the ingress multicast path bandwidth of the multicast forwarding paths into the switching fabric. When Multicast Path Management is disabled (the default), two paths are available:

When Multicast Path Management is enabled, an ingress multicast bandwidth policy can be used to manage the flow of multicast traffic through an MDA (IOM, IOM 2, or XMA) or the forwarding plane of an 2 x XP MDA IOM 3, IMM, or XCM.

The maximum number of bandwidth policies per NE is 32, including the default policy.

MDAs can be configured to use previously defined ingress multicast bandwidth policies. However, any path limits specified in the selected policy can be overridden for each MDA, if required.

Ingress multicast info policy

Ingress multicast info policies are used to define how each multicast channel is handled by NEs. The policy is assigned to a VPLS/VPRN service site or default routing instance, but the policy is actually used by the Ingress Multicast Bandwidth Manager, the ECMP Path Manager, and the Egress Multicast CAC Manager to determine the path through the switch fabric and to make decisions on joins to multicast streams.

The maximum number of ingress multicast info policies per NE is limited to 32, including the default policy.

MDAs can be configured to use previously-defined ingress multicast bandwidth policies. However, any path limits specified in the selected policy can be overridden for each MDA, if required.

Ingress multicast forwarding on L2-snooped and L3-routed IP multicast traffic can be explicitly configured by applying an ingress multicast info policy to a VPLS site (all types of VPLS are supported), a VPRN site, or the default routing instance.

An ingress multicast info policy consists of one or multiple named Bundles, which in turn, contain Channel ranges with possible overrides for individual channels.

Ingress multicast reporting policy

Ingress multicast reporting destination policies are used to specify the destination server for the collection of multicast reports. The policies are applied to residential subscriber IGMP policies.
