Tunneling, in general, is taking data (whether user data, routing
information, etc), encapsulating it in another protocol for travel (i.e.
TCP/IP), and sending it to a destination where the other end unwraps the
encapsulation and then uses the data (whether user data, routing
information, etc). D

tunnels, PIM register messages are tunnels, etc. That's just a brief
