‘Auto-RP’ is a Cisco propriety technology that automates distribution of multicast group to rendezvous point distribution in a PIM topology.
Auto-RP has some benefits:
- Makes it easier to use multi rendezvous points inside of a network to service different group ranges
- Allows for load splitting across multiple rendezvous points
- Simplifies rendezvous point placement towards the location of group participants
- Prevents inconsistent manual static rendezvous point configuration
- Multi rendezvous points can act as backups for the other rendezvous point
- The automatic rendezvous point technology has two basis components, candidate rendezvous points and rendezvous point mapping agents.
