Auto-RP is a Cisco proprietary protocol that uses two different roles: Candidate RP. Mapping Agent.
What is multicast auto-RP?
You can configure a more dynamic way of assigning rendezvous points (RPs) in a multicast network by means of auto-RP. When you configure auto-RP for a router, the router learns the address of the RP in the network automatically and has the added advantage of operating in PIM version 1 and version 2.
What is RP in sparse mode?
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 the purpose of RP in PIM?
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.
How does PIM SSM work?
PIM source-specific multicast (SSM) uses a subset of PIM sparse mode and IGMP version 3 (IGMPv3) to allow a client to receive multicast traffic directly from the source. PIM SSM uses the PIM sparse-mode functionality to create an SPT between the receiver and the source, but builds the SPT without the help of an RP.
What is static RP?
Understanding Static RP Protocol Independent Multicast (PIM) sparse mode is the most common multicast protocol used on the Internet. When you configure the static RP, the RP address that you select for a particular group must be consistent across all routers in a multicast domain.
What is Anycast RP?
Using Anycast RP is an implementation strategy that provides load sharing and redundancy in Protocol Independent Multicast sparse mode (PIM-SM) networks. Anycast RP allows two or more rendezvous points (RPs) to share the load for source registration and the ability to act as hot backup routers for each other.
What is RP address?
Configures a device interface as a rendezvous point (RP).
What is ip PIM RP address?
ip pim rp-address Configures a static IP address of a rendezvous point for a multicast group range or adds new multicast range to existing RP. The no form of the command removes the rendezvous point for a multicast group range or removes all configuration of the RP.
Does SSM need Rp?
Using sparse mode our receivers require the RP (Rendezvous Point) to discover new sources in the network. SSM (Source Specific Multicast) requires IGMPv3 and lets us join multicast groups from specified source addresses. Besides just joining any group, the receiver is able to receive the group from a specified source.
What is auto-RP and how does it work?
This lesson is about Auto-RP so we’ll cover BSR in another lesson. Auto-RP is a Cisco proprietary protocol that uses two different roles: The candidate RP is a router that announces itself that it wants to be an RP for the network. It does so by sending RP announcement packets to the 224.0.1.39 multicast address.
What is the difference between auto-RP and BSR?
Auto-RP and BSR are the dynamic ways to distribute RP information to other routers in the PIM SM domain, unlike the configuration of Static RP on all the routers which is a laborious task in scalable networks. Auto-RP uses two terms – Candidate RP and Mapping Agents.
Does configuring a sink RP interfere with auto-RP?
Configuring a sink RP does not interfere with Auto-RP operation because, by default, Auto-RP messages supersede static RP configurations. We recommend configuring a sink RP for all possible multicast groups in your network, because it is possible for an unknown or unexpected source to become active.
Can CCIE test auto-RP configs?
Even though BSR is the most common deployment type, from CCIE lab exam point of view Cisco can test Auto-RP configs as it is Cisco proprietary method. In both methods multiple routers (to provide redundancy) can be configured as RP (Candidate-RP).
