Multicast rendezvous point

Quick Definition: A rendezvous point is a router that acts as the place where sources and receivers of multicast data can find each other. On small networks, it's not hard to imagine finding the source of a multicast and subscribing to it.

What is the purpose of RP in PIM?

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.

Why do we need RP 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.

What is RP in Cisco?

Route Processor Overview

The route processor (RP) card is the system controller for the Cisco CRS 4-slot line card chassis. It performs route processing and distributes forwarding tables to the MSCs. Although the routing system contains two RP cards, only one RP is active at a time.

Which mode of PIM uses a rendezvous point?

To solve this issue, PIM sparse mode uses a RP (Rendezvous Point) in the network. Here's how it works: Each router that receives multicast traffic from a source will forward it to the RP. Each router that wants to receive multicast traffic will go to the RP.

What is RP mapping?

RP mapping agents store the information that is embedded in the RP announcements in a cache inside a group-to-RP mapping. The RP mapping agents join a multicast group 224.0. 1.39, where they receive the RP announcements. RP MAs send advertisements to a popular multicast group known as Cisco-RP-Discovery (224.0. 1.40).

How does multicast select RP?

The mapping agent listens to the RP announcement packets from our RP candidates and makes a list of all possible RPs. It will then elect an RP and informs the rest of the network with RP mapping packets that are sent to multicast address 224.0. 1.40.

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 does multicast RPF work?

Multicast RPF

In multicast routing, the decision to forward traffic is based upon source address and not on destination address as in unicast routing. It does this by utilizing either a dedicated multicast routing table or, alternatively, the router's unicast routing table.

What is multicast distribution tree between RP and receiver?

Shared Tree

The RP is the point at which hosts/receivers join to learn of active sources. Multicast sources must transmit their traffic to the RP. When receivers join a multicast group on a shared tree, the root of the tree is always the RP, and multicast traffic is transmitted from the RP down toward the receivers.

What is RPS on Cisco switch?

CISCO RPS 675 REDUNDANT POWER SYSTEM

Less than 60 µs failover capability prevents switch reboot after an internal switch power failure. Supports traditional Ethernet switches (12V output) and new inline powered Ethernet switches (-48V output) for voice-over-IP (VoIP) telephones.

What is RPL in Cisco?

This module describes the Cisco IOS XR software routing policy language (RPL) commands used to create, modify, monitor, and maintain routing policies.

What is RP in PIM Sparse Mode?

PIM Sparse Mode uses a special router called a Rendezvous Point (RP) to connect the flow source or multicast tree to the router next to the wannabe receiver. The RP is typically used only temporarily, as we'll see below. There can be different RP's for different multicast groups, which is one way to spread the load.

What is auto RP in multicast?

What is Rp CPU?

The route processor (RP) card is the system controller for the Cisco CRS Carrier Routing System. It performs route processing and distributes forwarding tables to the MSCs. The RP provides a control path to each MSC, performs system-monitoring functions, and contains hard disks for system and error logging.

What does IP PIM passive do?

PIM Passive allows you to specify that the interface is "passive" in regards to PIM. No PIM control packets are sent or processed (if received), but hosts can still send and receive multicast traffic and IGMP control traffic on the interface.

What is Rendezvous point?

Rendezvous Point or “RP” means a point in the network where Multicast receiver sites can register their interest to receive Multicast traffic.

What is the difference between PIM sparse and dense mode?

One of the primary difference between Dense and Sparse mode is the multicast technique used. In Dense mode packets are flooded to the entire network and then branches where there are no receivers are eliminated. In Sparse mode packets branches distribution growth as new nodes join the multicast group.

What is the difference between PIM and IGMP proxy?

IGMP snooping allows a device to only forward multicast streams to the links on which they have been requested. PIM Sparse mode requires specific designated routers to receive notification of all streams destined to specific ranges of multicast addresses.
