  2. Routing table - Wikipedia

    en.wikipedia.org/wiki/Routing_table

    The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet. To do this, a router needs to search the routing information stored in its routing table. The routing table contains network/next hop associations. These associations tell a router that a particular ...

  3. Router (computing) - Wikipedia

    en.wikipedia.org/wiki/Router_(computing)

    A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the ...

  4. Routing protocol - Wikipedia

    en.wikipedia.org/wiki/Routing_protocol

    Routers perform the traffic directing functions on the Internet; data packets are forwarded through the networks of the internet from router to router until they reach their destination computer. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly.

  5. route (command) - Wikipedia

    en.wikipedia.org/wiki/Route_(command)

    -n: Bypasses translating IP addresses to symbolic host names-q: Suppresses all output-v: Verbose; COMMAND: The command to run (add, delete, change, get, monitor, flush)-net: <dest> is a network address-host: <dest> is host name or address (default)-netmask: the mask of the route <dest>: IP address or host name of the destination

  6. nslookup - Wikipedia

    en.wikipedia.org/wiki/Nslookup

    nslookup operates in interactive or non-interactive mode. When used interactively by invoking it without arguments or when the first argument is - (minus sign) and the second argument is a hostname or Internet address of a name server, the user issues parameter configurations or requests when presented with the nslookup prompt (>).

  7. ICMP Router Discovery Protocol - Wikipedia

    en.wikipedia.org/wiki/ICMP_Router_Discovery_Protocol

    The ICMP Router Advertisement message is sent by a router on the local area network to announce its IP address as available for routing. When a host boots up, it sends solicitation messages to IP multicast address 224.0.0.2. [4] In response, one or more routers may send advertisement messages.

  8. IP routing - Wikipedia

    en.wikipedia.org/wiki/IP_routing

    The IP forwarding algorithm is a specific implementation of routing for IP networks. In order to achieve a successful transfer of data, the algorithm uses a routing table to select a next-hop router as the next destination for a datagram. The IP address of the selected router is known as the next-hop address. [1] The IP forwarding algorithm ...

  9. Enhanced Interior Gateway Routing Protocol - Wikipedia

    Number in range 1 to 255; 255 being the most reliable MTU Minimum path Maximum Transmission Unit (MTU) (never used in the metric calculation) Hop Count Number of routers a packet passes through when routing to a remote network, used to limit the EIGRP AS.
