What is the rendezvous point?

Rendezvous Point Overview. A rendezvous point (RP) is required only in networks running Protocol Independent Multicast sparse mode (PIM-SM). The protocol is described in RFC 2362. An RP acts as the meeting place for sources and receivers of multicast data. In a PIM-SM network, sources must send their traffic to the RP.

How do I set up auto-RP?

To configure auto-RP properties:

1. Configure PIM in sparse-dense mode on all routing devices in the PIM domain.
2. Configure a routable loopback interface address on all routing devices in the PIM domain.
3. Configure the two multicast dense groups on all the routing devices.
4. Configure the auto-RP announce option.

What is Rp multicast?

An RP acts as the meeting place for sources and receivers of multicast data. In a PIM-SM network, sources must send their traffic to the RP. This traffic is then forwarded to receivers down a shared distribution tree.

What is the IPv4 address for rendezvous point?

In this case “239.1.1.1,” which is the P-Group address (Default MDT), is registered. The register state also indicates that PE1 (IPv4 address 10.254.71.51) has made the registration. Figure 2.81. RP registration details. Check for the PIM joins under the PIM Master instance.

What is the inefficiency of the rendezvous point approach?

The inefficiency of the approach lies in the fact that all messages must first be routed to the RP before they reach the group members. In CoopNet and SplitStream, the source stream is “split” into multiple substreams or descriptions.

How is a rendezvous point used in multicast?

The single tree-based multicast system uses a Rendezvous Point (RP) based message dissemination scheme. That is, a sender of the multicast group sends a message to the root or the RP node of the tree, which then forwards the message along the tree to all receivers.
