BGP which stands for Border Gateway Protocol
BGP means BORDER GATEWAY PROTOCOL, UNDERSTOOD??
BGP border gateway protocol is the most commoly use exterior gateway protocol. EGP are used by ISP's and are being routed from a private network to the internet and to its destination private network.
BGP is always used as the routing protocol of choice between ISPs (external BGP) but also as the core routing protocol within large ISP networks (internal BGP).
IP (Internet Protocol)
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.
generally static routing protocol has the most trustworthy administrative distance .i.e; 1 and in dynamic routing protocols EIGRP has the best AD.

The commonly used protocols are the TCP/IP protocol suite. This is a set of protocols that work together, not a single protocol.
Routers that run a link-state protocol can establish a complete topology of the network. The shortest path first algorithm is used.
