Routing is of two types static and dynamic . In dynamic routing there are two protocols interior and exterior. Interior routing is inside an autonomous system and Exterior routing is between an autonomous system.RIP is short for routing information protocol. RIP is an interior protocol that is used inside an autonomous system.
The protocols used to distribute routing information between AS's are known as Exterior Gateway Protocols (EGP's).
Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.
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.
We use igrp in a autonomous system and we use eigrp between two autonomous systems.
sharing network information between routers
BGP stands for Border Gateway Protocol, which is the protocol used to exchange routing information between different autonomous systems (AS) on the internet. It is a crucial component of the internet's routing infrastructure, allowing diverse networks to communicate and share information about reachable IP addresses. BGP uses a path vector mechanism to maintain the path information that gets updated dynamically as the network topology changes. This enables efficient routing decisions and helps manage traffic flow across the internet.

Routing Information Protocol (RIP)
Open Shortest Path First (OSPF) is a type of routing protocol known as an interior gateway protocol or an interior routing protocol. The routers in an internet are responsible for receiving and forwarding packets through the interconnected set of networks. Each router makes routing decisions based on knowledge of the topology and traffic/delay conditions of the internet. The routing protocol between routers is used to exchange topology and traffic delay information. An interior routing protocol is used within a portion of the internet called an autonomous system, which simply means a connected set of routers that are managed by a single organization. OSPF is the most commonly used interior routing protocol.
Autonomous network means its a private network working independently on the field, ARS will automatically reconfigure the network settings with the previous successful transmission from the routing table .
