CGMP on Catalyst Switches for IP Multicast CGMP is a Cisco-developed protocol used on device connected to Catalyst switches to perform tasks similar to those performed by IGMP. CGMP is necessary for those Catalyst switches that do not distinguish between IP multicast data packets and IGMP report messages, both of which are addressed to the same group address at the MAC level.

Auto-RP and BSR. If your network includes routers from other vendors, configure the Auto-RP mapping agent and the BSR on a Cisco PIMv2 device. Ensure that no PIMv1 device is located in the path a between the BSR and a non-Cisco PIMv2 device.
Page 136: Pim Versions
PIMv1 and PIMv2 Interoperability To avoid misconfiguring multicast routing on your device, review the information in this section. The Cisco PIMv2 implementation provides interoperability and transition between Version 1 and Version 2, although there might be some minor problems. You can upgrade to PIMv2 incrementally. PIM Versions 1 and 2 can be configured on different routers and multilayer devices within one network.
Page 137: Pim Modes
Configuring PIM PIM Modes We recommend that you use PIMv2. The BSR function interoperates with Auto-RP on Cisco routers and Note multilayer devices. When PIMv2 devices interoperate with PIMv1 devices, Auto-RP should have already been deployed. A PIMv2 BSR that is also an Auto-RP mapping agent automatically advertises the RP elected by Auto-RP. That is, Auto-RP sets its single RP on every router or multilayer device in the group.

If a static RP configuration is used, then the configuration needs to be applied on all the routers in the multicast network. To automate this process, the Auto-RP protocol was devised. IP Multicast Routing Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3650 Switches) OL-29890-01...
Page 140: The Role Of Auto-Rp In A Pim Network
This Cisco proprietary feature eliminates the need to manually configure the RP information in every router and multilayer device in the network. For Auto-RP to work, you configure a Cisco router or multilayer device as the mapping agent. It uses IP multicast to learn which routers or devices in the network are possible candidate RPs to receive candidate RP announcements.

Auto-RP message before the Auto-RP message is forwarded. Auto-RP Benefits Auto-RP uses IP multicast to automate the distribution of group-to-RP mappings to all Cisco routers and multilayer devices in a PIM network. Auto-RP has these benefits: • Easy to use multiple RPs within a network to serve different group ranges.

Page 254: Restrictions For Configuring Ssm
Restrictions for Configuring SSM The following are the restrictions for configuring SSM: • To run SSM with IGMPv3, SSM must be supported in the Cisco IOS router, the host where the application is running, and the application itself. • The SSM mapping feature does not have all the benefits of full SSM. Because SSM mapping takes a group join from a host and identifies this group with an application associated with one or more sources, it can only support one such application per group.
Page 255: Information About Ssm
SSM is a datagram delivery model that best supports one-to-many applications, also known as broadcast applications. SSM is a core networking technology for the Cisco implementation of IP multicast solutions targeted for audio and video broadcast application environments. The device supports the following components that support SSM implementation: •...
Page 256: Ssm Operations
Therefore, routers that are not last-hop routers can run PIM-SM for SSM groups (for example, if they do not yet support SSM). • No MSDP source-active (SA) messages within the SSM range are accepted, generated, or forwarded.

Page 257: Benefits Of Source Specific Multicast
• The ability to provide Internet broadcast services through SSM without the need for unique IP multicast addresses allows content providers to easily offer their service (IP multicast address allocation has been a serious problem for content providers in the past).

IP address resource records and uses them as the source addresses associated with this group. SSM mapping supports up to 20 sources for each group.

(RP) addresses for (*, G) states, can be used to achieve a reasonable form of load balancing. This limitation applies equally to the per-flow load splitting in Cisco Express Forwarding (CEF) or with EtherChannels: As long as there are only a few flows, those methods of load splitting will not result in good load distribution without some form of manual engineering.
