vlsm subnetting

implementation mechanisms are different. Vlsm and CIDR also aim to adjust the subnet mask length. However, NAT technology allows organizations to use non-Global IP addresses to access the Internet by converting addresses into globally routable IP addresses. This reduces the need for public IP addresses. Nat runs on the routing device between the Intranet and the Internet, and the address in the packet is converted during communication between the Int

Send the datagram out from the corresponding interface the router's function routing selection and forwarding (switching) classless routing: A process of aggregating multiple networks with a bit mask into a single network address. Variable-length subnet mask: (VLSM) an organization uses multiple subnet masks in the same network address space to

On average, each person has hundreds of millions and hundreds of millions of people ...... Enough ~IPv6 addresses starting with 2002 are used to convert v4, followed by v4 addresses in hexadecimal notation;I have a more perceptual knowledge of anycast, which means that data needs to be sent to the RP first, and then the target host needs to be retrieved from the RP;The

an industrial standard in Early 1990s S. It is a typical Link Status Protocol. The main features of OSPF include: support for vlsm (long subnet mask), fast convergence, low bandwidth usage, and so on. The OSPF protocol exchanges link status information between neighbors so that the router can establish a link status database (LSD). Then, the router uses SPF (Shortest Path First, Shortest Path First) based on the information in the database) calculate

region is composed of one or more subnets connected to each other and is connected to the main region. In addition, the OSPF protocol supports a variable length subnet latency (vlsm) that provides network address space conversion and bandwidth-based computing. External Routing Protocol The external routing protocol provides routes between autonomous systems. The most common types of TCP/IP networks are as follows: EGP The first generation of the wide

However, if a class B address is used, only 500 of the 60,000 + host addresses are used, resulting in a la

First, the OSPF characteristics: 1.IETF Standard: Open room agreement, supported by different manufacturer's equipment 2. No loop by protocol: the implementation of SPF algorithm, will not produce loops 3. No class routing protocol: Support for VLSM and CIDR 4. Have unrestricted hop count: can be applied with large network 5. Level: Easy to expand, router burden will not increase with the size of the network increased dramatically 6. Regionaliza
