Multicast ip pim autorp listener

When using the Auto-RP feature, in order to ensure that traffic for the 224.0.1.39 and 224.0.1.40 Auto-RP groups is flooded using PIM dense mode, you can use one of two solutions:

  • Use PIM sparse-dense mode and specify the two Auto-RP groups as groups that will be using dense mode
  • Use the ip pim autorp listener command to ensure that multicast traffic that is sent to 224.0.1.39 and 224.0.1.40 gets flooded with dense mode.
