WebPIM uses Hello messages to discover neighbors and form adjacencies. The Hello is sent to the All-PIM-Routers local multicast address, 224.0.0.13, every 30 seconds (PIMv1 uses AllRouters, 224.0.0.2). Each LAN has a PIM Designated Router … WebThe source DR sends PIM register messages from the source network to the RP. Neighboring PIM routers multicast periodic PIM hello messages to each other every 30 seconds (the default). The PIM hello message usually includes a holdtime value for the neighbor to use, but this is not a requirement.
