SEMESTER 2 Chapter 6 VLSM and CIDR

SEMESTER 2 Chapter 6 VLSM and CIDR V 4.0

6.1.1 Why were VLSM, CIDR, NAT, We would have run out of ip addresses and private addressing developed? 6.1.1.2 What is the range for Class A 0.0.0.0-127.255.255.255 addresses? What is the range for Class B 128.0.0.0-191.255.255.255 addresses? What is the range for Class C 192.0.0.0-223.255.255.255 addresses? What are ip addresses that Future use begin with 4 1 bits reserved for? 6.1.1.3 How many hosts are available 254 for Class C addresses? 6.1.2 How can you determine the The first octet subnet mask for a classful ip address? 6.1.3 How many host addresses are 65,534 available for Class B addresses? What two things did Classless More efficient use of IPv4 address space Inter-Domain Routing (CIDR) Prefix aggregation, which reduced the size of routing allow for? tables What does the address class Nothing mean to CIDR? 6.1.3.2 What process does CIDR Variable Length Subnet Masks (VLSM) allocate IP addresses according to subnets rather than by class? What does prefix aggregation Decreases the size do to the routing tables? What is another name for a Supernet route route that has been aggregated be called? What must be included in the The subnet mask routing update when you use classless routing? 6.1.4 What are the 5 classless RIPv2, EIGRP, OSPF, IS-IS, and BGP routing protocols? When are classless routing when the mask cannot be assumed or determined by protocols necessary? the value of the first octet Do you have to use route No summarization in a classless routing environment? 6.2.1 What is another name for Subnetting a subnet VLSM? Sub-subnetting 6.2.2 If you start with /16 subnet, how 28 = 256 subnets many subnets are available? If sub-subnet a /16 subnet, to / 212 = 4,096 per subnet 28 how many subnets are created for each of the original subnets? 6.3.1 What is the process of Route aggregation advertising a contiguous set of Route summarization addresses as a single address Supernetting with a less-specific, shorter subnet mask called? Explain the difference between Supernetting ignores the limitation of classful route summarization in RIPv1 boundaries, whereas RIPv1 summarizes to the single and supernetting? major network classful address 6.3.2 When you summarize a set of List all the networks in binary routes what is the first step? What is matched in the second Match the left-most bits to get the summary address step of route summarization? What is the final step in route Copy all the matching bits and place zeros after them summarization? to determine the summarized network address
