What is multicast auto RP?
What is multicast auto RP?
The auto-RP mechanism is one way that a multicast router can learn the set of group-to-RP mappings. Auto-RP automatically distributes mapping information to routing devices. It simplifies use of multiple RPs for different multicast group ranges, thus allowing multiple RPs to act as backups for each other.
How do I enable multicast on my Cisco router?
Perform these configurations to enable multicast routing on a router:
- Issue the ip multicast-routing command globally on the router.
- Enable PIM sparse or dense mode, by issuing the ip pim sparse-dense-mode command on all the multicast interfaces.
- In the case of sparse mode, a Rendezvous Point (RP) is to be configured.
What is the IP address for the Cisco RP announce multicast group?

The RP messages are sent every 60 seconds to the multicast IP group 224.0. 1.39, known as Cisco-RP-Announce.
What is the role of RP in PIM?
The RP is the multicast router that is the root of the PIM-SM shared multicast distribution tree. D. The RP responds to the PIM join messages with the source of a requested multicast group.
What is IGMP snooping in router?
IGMP snooping is a method that network switches use to identify multicast groups, which are groups of computers or devices that all receive the same network traffic. It enables switches to forward packets to the correct devices in their network.
What is purpose of RP in PIM?
When the RP receives the PIM join, it will start forwarding the multicast traffic. This concept of joining the RP is called the RPT (Root Path Tree) or shared distribution tree. The RP is the root of our tree which decides where to forward multicast traffic to.
How do I know if multicast is working?
PROCEDURE. In order to verify if Multicast is working correctly in your network, you can use the following quick tcpdump/ping test. If the Multicast is working correctly then you should see packets arriving at the first node. Repeat this procedure in each node to verify that Multicast is OK in your network.
Is multicast enabled by default on Cisco switches?
By default, multicast routing is disabled, and there is no default mode setting. This procedure is required. You must configure the PIM version and the PIM mode. The switch populates its multicast routing table and forwards multicast packets it receives from its directly connected LANs according to the mode setting.
