An exterior gateway protocol is a routing protocol used to exchange routing information between autonomous systems. This exchange is crucial for communications across the Internet. Notable exterior gateway protocols include Exterior Gateway Protocol (EGP), now obsolete, and Border Gateway Protocol
List of Exterior gateway protocol (EGP)
- EGP use for exchanging routing information between autonomous system or domains.
- Exterior gateway protocols are use to connect two ISPs.
- They are widely use on Internet.
- BGP is the only exterior gateway protocol.
You use the Exterior Gateway Protocol to exchange network reachability information between routers in different autonomous systems. An interior gateway protocol (IGP), such as RIP or OSPF, is used within an AS to facilitate the communication of routing information within an autonomous system.

Frequent Questions – 💬
❓ What does Exterior Gateway Protocol mean?
Exterior Gateway Protocol (EGP) is used to exchange net-reachability information between Internet gateways belonging to the same or different autonomous systems. EGP was developed by Bolt, Beranek and Newman in the early 1980s. It was first described in RFC 827 and formally specified in RFC 904 (1984).
❓ What is Exterior Gateway Protocol (EGP)?
EGP mechanisms are:
- Acquire neighbors
- Monitor neighbors
- Exchange data as update messages
❓ What is exterior border Gateway Protocol?
- The peer is listening for a Keepalive message from its peer.
- If a Keepalive message is received and no timer has expired before reception of the Keepalive, BGP transitions to the Established state.
- If a timer expires before a Keepalive message is received, or if an error condition occurs, the router transitions back to the Idle state.

Is BGP an exterior gateway protocol?
“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.”

What is IGP and EGP protocol?
An interior gateway protocol (IGP) is a routing protocol that is used to exchange routing information within an autonomous system (AS). In contrast, an Exterior Gateway Protocol (EGP) is for determining network reachability between autonomous systems and makes use of IGPs to resolve routes within an AS.

What are the three routing protocols?
Routing protocols are mechansims by which routing information is exchanged between routers so that routing decisions can be made. In the Internet, there are three types of routing protocols commonly used. They are: distance vector, link state, and path vector.

Why OSPF is not used in exterior routing?
This full view does come with some downsides: greater memory and CPU resources being used. That's why OSPF is usually used for internal, rather than external, routing. Being an IGP, the overhead of being a link-state protocol is minimized due to the smaller topology.

Why is BGP used over OSPF?
BGP is considered to be more flexible as well as scalable than OSPF and it would be also used on a larger network. OSPF would be used to determine the fastest route whereas the BGP would be putting emphasis on determining the best path. Well, Because OSPF stub areas which would be a total mess to configure.
