What is Routing table

Question

What is Routing table? Explain it briefly.

Answer 1

The Routing Table is a table maintained in kernel which finds out how packets are routed to another system. The number of programs might add or delete routes from routing tables, comprising route, in.routed, ifconfig and in.rdisc. The routing table comprises of three kinds of routes: HOST ROUTES are checked initially and state a route to just one host. NETWORK ROUTES are checked after that and define a route to all hosts on one network. DEFAULT ROUTES are employed as a catch-all, whenever no host or network routes are found to a destination. They generally send to an additional knowledgeable routing machine that has a better chance of being capable to find a host or network route to destination.
