An example of route aggregation as a part of CIDR. A supernetwork, or supernet, is an Internet Protocol (IP) network that is formed by aggregation of multiple networks (or subnets) into a larger network. The new routing prefix for the aggregate network represents the constituent networks in a single routing table entry.
iproute2 is a collection of userspace utilities for controlling and monitoring various aspects of networking in the Linux kernel, including routing, network interfaces, tunnels, traffic control, and network-related device drivers.
IP forwarding algorithms in most routing software determine a route through a shortest path algorithm. In routers, packets arriving at an interface are examined for source and destination addressing and queued to the appropriate outgoing interface according to their destination address and a set of rules and performance metrics.

The letter "S" indicates that the route is a static route that has, for all intents and purposes, been added manually to the router process by the administrator and installed into the routing table.

In other words if A learns from B that the path to C is through B then it will not tell B to route packets destined for C through A. Likewise, a link-state routing protocol may keep a database containing the state of different links in the network, representing a "map" (so to speak) of the network. But the portion of the network whose routes ...
Routing protocols, according to the OSI routing framework, are layer management protocols for the network layer, regardless of their transport mechanism: IS-IS runs on the data link layer (Layer 2) Open Shortest Path First (OSPF) is encapsulated in IP, but runs only on the IPv4 subnet, while the IPv6 version runs on the link using only link ...
Distance-vector routing protocols use the Bellman–Ford algorithm.In these protocols, each router does not possess information about the full network topology.It advertises its distance value (DV) calculated to other routers and receives similar advertisements from other routers unless changes are done in the local network or by neighbours (routers).
