What is RP address in multicast?
Multicast PIM sparse mode requires an RP (Rendezvous Point) as a meeting point in the network for all multicast traffic.
What does RP address mean?
Abstract This memo defines an address allocation policy in which the address of the Rendezvous Point (RP) is encoded in an IPv6 multicast group address.
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.
What is the purpose of an RP in PIM CCNP?
In both methods multiple routers (to provide redundancy) can be configured as RP (Candidate-RP). These devices inform its interest to become RP to a Mapping Agent who then inform about this to rest of the network.
What is BSR and RP in multicast?
BSR (Bootstrap) is similar to Cisco’s AutoRP, it’s a protocol that we use to automatically find the RP (Rendezvous Point) in our multicast network. Candidate BSR: this is the router that collects information from all available RPs in the network and advertises is throughout the network.
What is the purpose of RP for multicast?
This concept of joining the RP is called the RPT (Root Path Tree) or shared distribution tree. The RP is the root of our tree which decides where to forward multicast traffic to. Each multicast group might have different sources and receivers so we might have different RPTs in our network.
What is the difference between PIM and IGMP?
Important is the Note: To use PIM snooping, you must enable IGMP snooping on the switch. IGMP snooping restricts multicast traffic that exits through the LAN ports to which hosts are connected. IGMP snooping does not restrict traffic that exits through the LAN ports to which one or more multicast routers are connected.
What is multicast auto RP?
Auto-RP requires multicast flooding to announce potential RP candidates and to discover the elected RPs in the network. Multicast flooding occurs through a PIM dense mode model, where group 224.0. 1.39 is used for announce messages and group 224.0. 1.40 is used for discovery messages.
How do I configure anycast network?
- Obtain an Autonomous System Number. The first step for setting up an anycast network is getting an autonomous system number (ASN).
- Acquire an IP Address. Now that you have an ASN, you can acquire an IP block to advertise.
- Find a Hosting Provider.
- Configure BGP.
How does IPv6 multicast work with embedded RP?
The embedded RP feature that works for IPv6 multicast is a cool trick that embeds the IPv6 address of the RP within the IPv6 multicast group address. By doing this, multicast enabled routers can extract the RP address just by looking at the multicast group address and use it for a shared tree.
What are embedded-RP addresses?
Addresses in the subrange will be called embedded-RP addresses. This scheme obviates the need for MSDP, and the routers are not required to include any multicast configuration, except when they act as an RP. This memo updates the addressing format presented in RFC 3306.
How do I get the RP address of a multicast router?
By doing this, multicast enabled routers can extract the RP address just by looking at the multicast group address and use it for a shared tree. The only router where you have to configure the RP address is on the RP itself…that’s it!
