Which mode of pim uses a source distribution tree?

PIM-DM only uses source-based trees. As a result, it does not use RPs, which makes it simpler than PIM-SM to implement and deploy. It is an efficient protocol when most receivers are interested in the multicast data, but does not scale well across larger domains in which most receivers are not interested in the data.

Which mode of PIM uses a rendezvous point RP )?

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.

Which routing technique use a source-based tree approach?

Multicast Routing using a Source-Based Tree.

What is the difference between PIM sparse mode and PIM 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 IP PIM dense mode?

Protocol Independent Multicast - Dense Mode (PIM-DM) is a data-driven multicast routing protocol, which builds source-based multicast distribution trees that operate on the Flood- and-Prune principle. It requires unicast-reachability information, but does not depend on a specific unicast routing protocol.

What is PIM passive mode?

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 does IP PIM sparse mode do?

PIM Sparse Mode (PIM-SM) is a multicast routing protocol designed on the assumption that recipients for any particular multicast group will be sparsely distributed throughout the network. In other words, it is assumed that most subnets in the network will not want any given multicast packet.

Which routing technique is used in a distributed system *?

Explanation: Distributed system uses fixed routing technique.

What are the 3 types of routing protocols?

Routing Information Protocol (RIP) Interior Gateway Protocol (IGRP) Open Shortest Path First (OSPF)

What is source based routing?

Source-based routing selects which gateway to direct outgoing client traffic through based on the source IP address in each packet header. When enabled, source-based routing automatically scans your network configuration to create client traffic rules.

What is dense mode in multicast?

Dense mode multicast is one mode that multicast can use to construct a tree for sending packets to the multicast subscribers. It is an alternative to sparse mode. The basic assumption behind dense mode is that the multicast packet stream has receivers at most locations. Sparse mode assumes relatively fewer receivers.

How does source specific multicast work?

Source-specific multicast (SSM) is a method of delivering multicast packets in which the only packets that are delivered to a receiver are those originating from a specific source address requested by the receiver. By so limiting the source, SSM reduces demands on the network and improves security.

What is IP PIM sparse dense mode in Cisco?

The 'ip pim sparse-dense mode' command enables PIM to operate in sparse or dense mode, depending on the multicast group. When you enable sparse-dense mode, the interface is treated as dense mode if the multicast group is in dense mode. If the group is in sparse mode, the interface is treated in sparse mode.

Which service provides a list of rendezvous points to PIM sparse mode routers?

PIM Bootstrap Router (BSR)

BSR is being used by PIM to discover and announce rendezvous point set information for all the group prefix to each multicast router in the PIM domain.

What is RP in multicast routing?

A rendezvous point (RP) is required only in networks running Protocol Independent Multicast sparse mode (PIM-SM). The protocol is described in RFC 2362. In PIM-SM, only network segments with active receivers that have explicitly requested multicast data will be forwarded the traffic.

What is the purpose of 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.

What is the role of the RP in PIM sparse mode 350 401?

What is the role of the RP in PIM sparse mode? A. The RP maintains default aging timeouts for all multicast streams requested by the receivers.

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 IP PIM sparse dense mode in Cisco?

The 'ip pim sparse-dense mode' command enables PIM to operate in sparse or dense mode, depending on the multicast group. When you enable sparse-dense mode, the interface is treated as dense mode if the multicast group is in dense mode. If the group is in sparse mode, the interface is treated in sparse mode.

Why multicast is used?

Multicast IP Routing protocols are used to distribute data (for example, audio/video streaming broadcasts) to multiple recipients. Using multicast, a source can send a single copy of data to a single multicast address, which is then distributed to an entire group of recipients.
