In computing, route is a command used to view and manipulate the IP routing table in Unix-like and Microsoft Windows [1] operating systems and also in IBM OS/2 and ReactOS. [2] Manual manipulation of the routing table is characteristic of static routing .
The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
A routing table is a database that keeps track of paths, like a map, and uses these to determine which way to forward traffic. A routing table is a data file in RAM that is used to store route information about directly connected and remote networks. Nodes can also share the contents of their routing table with other nodes.
Many Linux distributions have deprecated the use of ifconfig and route in favor of the software suite iproute2, such as ArchLinux [3] or RHEL since version 7, [4] which has been available since 1999 for Linux 2.2. [5] iproute2 includes support for all common functions of ifconfig(8), route(8), arp(8) and netstat(1). It also includes multicast ...
In computing, netstat is a command-line network utility that displays open network sockets, routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics. It is available on Unix, Plan 9, Inferno, and Unix-like operating systems including macOS, Linux ...
iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete net-tools utilities that provide the same functionality. [4] [5] Below is a table of obsolete utilities and their iproute2 replacements.
MTR also has a User Datagram Protocol (UDP) mode (invoked with "-u" on the command line or pressing the "u" key in the curses interface) that sends UDP packets, with the time to live (TTL) field in the IP header increasing by one for each probe sent, toward the destination host. When the UDP mode is used, MTR relies on ICMP port unreachable ...
Static routes are used with and without dynamic Routing protocols and usually share the same routing table as those protocols. [1] Routes require at least two attributes; the destination and the gateway, but may contain additional attributes such as a metric (sometimes called the administrative distance).
