  • Page 40: Static Route

    4.5.2 Static Route Static routing is the simplest form of network routing. It makes available to a switch/router to forward packets from predetermined ports through a predictable path into and out of a network. Static routing is solid, but does not address to the fluctuation in the network, therefore, it might result in destination net unreachable.
  • Page 41: Rip

    GigaX Series L3 Managed Switch User Guide Figure 18. Static Route 4.5.3 The Routing Information Protocol (RIP) is documented in RFC 1388 1723. In short, RIP is a distance-vector routing protocol that exchange routing information using UDP packets. RIP configuration includes the following information: RIP process: enable/disable.
  • Page 42: Bridge

    By default, RIP process is disabled and two of RIP Versions are assigned for the switch. All Layer 3 interfaces are classified as RIP enabled interfaces. Once the RIP process has been enabled, the current state of the active process will be displayed. You can click to refresh the updated status.

  • Page 113: Ip Addresses, Network Masks, And Subnets

    GigaX Series L3 Managed Switch User Guide IP Addresses, Network Masks, and Subnets IP Addresses This section pertains only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered. This section assumes basic knowledge of binary numbers, bits, and bytes.
  • Page 114: Table 8. Ip Address Structure

    The first part of every IP address contains the network ID, and the rest of the address contains the host ID. The length of the network ID depends on the network's class (see following section). Table 7 shows the structure of an IP address.
  • Page 115: Network Classes

    GigaX Series L3 Managed Switch User Guide 6.1.2 Network classes The three commonly used network classes are A, B, and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses and characteristics.
  • Page 116: Subnet Masks

    Subnet masks A mask looks like a regular IP address, but contains a pattern of bits that tells what parts of an IP address are the network ID and what parts are the host ID: bits set to 1 mean "this bit is part of the network ID" and bits set to 0 mean "this bit is part of the host ID."...
  • Page 117 GigaX Series L3 Managed Switch User Guide The two extra bits in Field 4 can have four values (00, 01, 10, 11), so there are four subnets. Each subnet uses the remaining six bits in field4 for its host IDs, ranging from 0 to 63.
