What is Routing

What is Routing : Processing of packets from one network to another network is known as routing. Basic components needed to route: • Routable Protocol (IPv4, IPv6, etc.) • Network address with  Subnet mask • Next Hop & Metric Points to Remember Router will only use routes with reachable “next hops” Routers will only use the “best” routes Routing protocols DO NOT send packets across the network. Their role is to determine the best path for routing. Routed protocols actually send the data, and the most common example of a routed protocol is IP. The routing table is concerned with two types of Layer-3 protocols: • Routed protocols - assigns logical addressing to devices, and routes packets between networks. Examples include IP and IPX. • Routing protocols - dynamically builds…
