  1. VLSM stands for
    Variable Length Subnet Masking
  2. The purpose VLSM was designed was to:
    Conserve IP addresses when using IPv4, maximizing the number of useable IP addresses available in a network
  3. Dynamic routing protocols that support VLSM include:
    OSPF•RIP v. 2•EIGRP•IS-IS
  4. VLSM is sometimes referred to as __________________________.
    Subnetting a subnet
  5. What is an “autonomous system”?
    it’s a network used in one enterprise
  6. What is meant by “route aggregation”?
    It’s the same thing as route summarization; it’s a way to summarize more than 1 route with one route entry in a router’s routing table.
  7. How can you take advantage of route aggregation using VLSM?
    Make sure your VLSM routes are not distant from each other. This wayroutes can be aggregated into one route in the routing table.
  8. Is RIP v. 1 a classful or classless protocol? RIP v. 2? What does this mean?
    RIP v. 1 is classful; RIP v. 2 is classless. It means that RIP v. 1 must staywithin the “normal” IP class system (A, B, C); classless means RIP v. 2 canuse VLSM.
