Multicast manager overview
Introduction
The CPAM multicast manager provides a centralized location for managing multicast domains. You can use the multicast manager to monitor, diagnose, and navigate to multicast objects in service provider multicast networks. The multicast manager allows you to quickly navigate to specific multicast objects—such as, PIM routing instances, groups, or interfaces.
The multicast manager provides a real-time view multicast objects in the network, such as:
The multicast topology view of the network is synchronized with the IGP domain. If you move an object on the IGP topology map, the same object moves on the multicast topology view.
Figure 17-2, Sample multicast topology view with highlighting shows a sample multicast topology view.
Multicast networks
A service provider multicast network typically includes a PIM domain which runs PIM/IGMP snooping, in addition to multiple services—such as an L2 domain.
A PIM domain is a contiguous set of routers that implement PIM and are configured to operate within a common boundary. One router in this domain is elected the BSR and all of the boot strap messages are flooded, hop by hop, until all of the PIM routers learn the same set of RPs.
Multicast services, such as VPLS, implement PIM or IGMP snooping.
The following figure shows a sample multicast network:
