What is the use of RT command?
The route command allows you to make manual entries into the network routing tables. The route command distinguishes between routes to hosts and routes to networks by interpreting the network address of the Destination variable, which can be specified either by symbolic name or numeric address.
What is the use of route in Linux?
route command in Linux is used when you want to work with the IP/kernel routing table. It is mainly used to set up static routes to specific hosts or networks via an interface.
What is ip route in Linux?
ip route is used to manipulate entries in the kernel routing tables. Route types: unicast – the route entry describes real paths to the destinations covered by the route prefix. unreachable – these destinations are unreachable. Packets are discarded and the ICMP message host unreachable is generated.
What is Dev route?
dev If force the route to be associated with the specified device, as the kernel will otherwise try to determine the device on its own (by checking already existing routes and device specifications, and where the route is added to). In most normal networks you won’t need this.
What is arp command?
Using the arp command allows you to display and modify the Address Resolution Protocol (ARP) cache. Each time a computer’s TCP/IP stack uses ARP to determine the Media Access Control (MAC) address for an IP address, it records the mapping in the ARP cache so that future ARP lookups go faster.
What does IP route display?
The show ip route command is a powerful tool to use at this point in your search. The output of show ip route displays the entries in the routing table, as well as the means by which they were determined (directly connected network, static route, or which routing protocol was used to select the route).
What is host name in Linux?
hostname command in Linux is used to obtain the DNS(Domain Name System) name and set the system’s hostname or NIS(Network Information System) domain name. A hostname is a name which is given to a computer and it attached to the network. Its main purpose is to uniquely identify over a network.
What does IP route show?
The output of show ip route displays the entries in the routing table, as well as the means by which they were determined (directly connected network, static route, or which routing protocol was used to select the route).
What is SRC in IP route?
The src attribute is a hint that is used by the address selection algorithm. It is significant when a host has multiple IP addresses, which is usually, but not always, when it has multiple interfaces.
