The whole idea of a routing protocol, such as RIP, is that routers learn about other networks (those that are not directly connected) automatically. This reduces the amount of configuration needed, and allows the routers to adapt to changing conditions. For example, if a certain route is not available, an alternate route - should one exist - will be enabled.

Flat routing protocol is a network communication protocol implemented by routers in which all routers are each other's peers. Flat routing protocol distributes routing information to routers that are connected to each other without any organization or segmentation structure between them. Flat routing protocols are primarily those that don't work under a predefined network layout and perimeter. They enable the delivery of packets among routers through any available path without considering network hierarchy, distribution and composition. Flat routing protocol is implemented in flat networks where each router node routinely collects and distributes routing information with its neighboring routers. The entire participating node addressed by flat routing protocol performs an equal role in the overall routing mechanism. Routing Information Protocol, Interior Gateway Routing Protocol and Enhanced Interior Gateway Routing Protocol are popular examples of flat routing protocols.
Autonomous System Numbers (ASNs) are globally unique numbers that are used to identify autonomous systems (ASes) and which enable an AS to exchange exterior routing information between neighboring ASes. An AS is a connected group of IP networks that adhere to a single and clearly defined routing policy.
Dynamic routing protocols are "languages" routers use to communicate the details and status of networks to which they are connected. Examples include RIP, OSPF, EIGRP, BGP and IS-IS.They are called dynamic because they can respond to network changes, such as a failed link, a new link or in some cases a change to a link (perhaps a changed bandwidth value). This is in contrast to a static route, which an administrator must type in manually and which cannot automatically respond to network changes.Two routers must be running the same routing protocol to exchange route information; RIP cannot talk directly to OSPF, for example. The router admin must enable the routing protocol, then instruct the router which of its connected networks it should advertise to other routers running the same protocol.

An internetwork is a collection of individual networks, such as LANs or WANs, connected by routers to enable communication across different networks. It allows devices on different networks to exchange data by forwarding packets between them. The internet is a prime example of a vast internetwork connecting millions of networks worldwide.
if a protocol is only classfull(RIPv1, IGRP) the command will have no effect, but in protocols that support vlsm and classless ip adressing it will enable the protocol to send the subnet mask in it's packets so that a router would not recognize only class networks, but also their subnets.
It is desirable to allow packets with the same source and destination to take more than one possible path. This facility can be used to ease congestion and overcome node failures. To operate such a scheme consistently nodes must maintain routing tables specifying what goes where. The mechanisms for this differ with datagram and virtual circuittransport.In flow-based networking, packets are routed as whole flows, i.e. streams of related packets, rather than as individual packets as in current IP/MPLS networks. The unique level of data obtained in flow-based routing, such as flow length, rate, delay variation and other parameters, enable a number of new network benefits.
