What is a PIM neighbor?
What is a PIM neighbor?
Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. PIM uses the unicast routing table for reverse-path forwarding.
What address do PIM routers listen to in order to automatically discover the best RP for each multicast group?
The RP Discovery Messages destined to 224.0. 1.40 contain the best elected RP-to-group mapping information from Mapping Agents. All the PIM routers join the multicast group 224.0.
What is auto RP Cisco?
Auto-RP is a Cisco proprietary protocol that uses two different roles: Candidate RP. Mapping Agent.
What is the IP address for the Cisco RP announce multicast group?
The candidate RPs declare their existence to the mapping agent by sending an announce message on the fixed multicast address 224.0. 1.39, known as the “Announcement Group”.
What is MSDP used for?
The Multicast Source Discovery Protocol (MSDP) is used to connect multicast routing domains. It typically runs on the same router as the Protocol Independent Multicast (PIM) sparse-mode rendezvous point (RP).
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.
How do you set PIM RP?
To configure PIM sparse mode and the RP static IP address:
- Configure PIM.  [email protected]# edit protocols pim.
- Set the interface value. [edit protocols pim] [email protected]# set pim interface all.
- Disable PIM on the network management interface.
- Configure RP.
- Configure the IP address of the RP.
How do I set up auto-RP?
To configure auto-RP properties:
- Configure PIM in sparse-dense mode on all routing devices in the PIM domain.
- Configure a routable loopback interface address on all routing devices in the PIM domain.
- Configure the two multicast dense groups on all the routing devices.
- Configure the auto-RP announce option.
How do I set up auto RP?
Why do we need MSDP?
MSDP is a mechanism that allows RPs to share information about active sources. RPs know about the receivers in their local domain. When RPs in remote domains hear about the active sources, they can pass on that information to their local receivers and multicast data can then be forwarded between the domains.
What does MSDP stand for?
Multicast Source Discovery Protocol (MSDP) is a Protocol Independent Multicast (PIM) family multicast routing protocol defined by Experimental RFC 3618.
