What is the destination address for RP bootstrap messages?

Answer: 224.0.0.13.

CCNP / BCMSN:

You see the command ip unnumbered ethernet0 on a Serial interface. What exactly does that command mean?

Answer: The Serial interface is in effect using the IP address assigned to the Ethernet address. A good command to know, but use with care.
