1. What benefit does dynamic routing offer?

2. Consider a WAN with two packet switches. Assume each switch has a forwarding table entry for each local address (i.e., the address of each computer that attaches to the switch) plus a default entry that points to the other switch. Under what circumstances will the scheme work? Under what circumstances will the scheme fail?

3. What are the two basic approaches used to perform a distributed route computation, and how does each work?
