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.
How does multicast PIM Sparse Mode work?
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.
What is the difference between PIM and IGMP?
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.
Can 2960x do Layer 3?
These switches also provide Layer 3 routing capability, application-aware intelligence, and double the scale. They are the greenest Cisco Catalyst access switches ever.
What is the difference between PIM sparse and dense mode?
PIM sparse mode: this is a “pull” model where we only forward multicast traffic when requested. PIM dense mode: this is a “push” model where we flood multicast traffic everywhere and then prune it when it’s not needed.
How does PIM dense mode work?
PIM Dense Mode (PIM-DM) uses dense multicast routing. It implicitly builds shortest-path trees by flooding multicast traffic domain wide, and then pruning back branches of the tree where no receivers are present. PIM-DM is straightforward to implement but generally has poor scaling properties.
What is PIM sparse mode vs dense mode?
What is the role of the RP in PIM sparse mode?
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 the difference between sparse and dense mode?
Sparse mode assumes relatively fewer receivers. Dense mode is ideal for groups where many of the nodes will subscribe to receive the multicast packets, so that most of the routers must receive and forward these packets (groups of a high density).
What does a PIM system do?
A Product Information Management (PIM) solution is a business application that provides a single place to collect, manage, and enrich your product information, create a product catalog, and distribute it to your sales and eCommerce channels.
