A routing table contains the path information for data data packets to reach a particular inter-network. Basically this table consists of the following information,
Network ID, Subnet Mask, Gateway Address, Interface(port), and netric(hops or number of gaps between two internetworking devices).

Routers add entries to routing table with the help of routing protocols.
