Routing service includes - Static routing, source to destination routes, RIP, IGRP, OSPF, BGP protocols configuration and addition of networks in configured protocols.
Routing is the process of defining rules for selecting a path for network traffic in single or across multiple networks. Routing directs network packets from their source toward their destination through intermediate network nodes by specific packet forwarding mechanisms such as static routing or dynamic routing. A Interior gateway routing protocol such as OSPF, RIP, EIGRP, IS-IS normally used for routing within a autonomous network while external gateway routing protocol such as BGP normally used for routing between autonomous network.
