A PIM protokoll működési elvei
A PIM protocol is a set of protocols for transmitting multicast in networks between routers. Neighbor relationships are established similarly to dynamic routing protocols. PIMv2 sends Hello messages every 30 seconds to the reserved multicast address 224.0.0.13 (All-PIM-Routers). The message includes Hold Timers—usually equal to 3.5*Hello Timer, which is 105 seconds.
