EBGP (Exterior Border Gateway Protocol) and IBGP (Interior Border Gateway Protocol) are two different routing protocols used to exchange routing information between different autonomous systems.

EBGP is used to connect networks between different autonomous systems, while IBGP is used to connect networks within the same autonomous system.

The main difference between EBGP and IBGP is that EBGP does not require a full mesh of routers, while IBGP does.

Additionally, EBGP uses an AS_PATH attribute for loop prevention, whereas IBGP does not.

Furthermore, EBGP sends updates over TCP port 179 and uses a hop-by-hop approach for path selection; on the other hand, IBPG sends updates over TCP port 179 and uses a recursive approach for path selection.

Explaining EBGP in Detail

External BGP (EBGP) is a routing protocol used to exchange information between autonomous systems, or networks, on the internet. EBGP is used to share information about how to reach destinations outside of an organization’s network. It is the most widely used exterior routing protocol and it helps ensure that packets are delivered efficiently from one autonomous system to another.

In order for EBGP to work properly, it must be configured correctly. This includes setting up the correct EBGP configuration parameters such as neighbor addresses, AS number  and authentication methods. It also involves making sure that the proper protocols are in place for exchanging routing information between autonomous systems. With this in mind, it is important for network administrators to understand how EBGP works and how to configure it correctly in order for their networks to function optimally.

Explaining IBGP in Detail

Internal Border Gateway Protocol (IBGP) is an interior routing protocol that allows routers within an autonomous system to exchange route information.

It is used to ensure that all routers in the same autonomous system are aware of each other's routes and can make decisions about how best to route traffic internally.

IBGP is a critical component of any network infrastructure, as it ensures that all internal routers have the same view of the network topology and can make optimal routing decisions.

Advantages & Disadvantages of EBGP

The biggest advantage of using EBGP is its scalability. The protocol can handle large amounts of data and route it quickly and efficiently without any interruption in service. This makes it ideal for applications that require high levels of throughput.

As businesses and organizations grow, scalability is an important factor to consider. Using EBGP (External Border Gateway Protocol) allows for a high level of scalability by enabling automatic route advertisement between multiple autonomous systems. This protocol can be used to exchange routing information between two or more autonomous systems, allowing for more efficient communication and increased scalability. With the use of EBGP, organizations can create a larger network with fewer resources and maximize their bandwidth usage.

Moreover, it has built-in security features which enable secure communication between autonomous systems without requiring additional hardware or software implementations.

On the other hand, there are some drawbacks associated with using EBGP for packet routing.

First, it can be quite complex to configure and maintain due to its reliance on manual configuration from network administrators. Additionally, because it relies on multiple IP addresses per router, there is an increased risk of misconfiguration when compared to simpler protocols such as

Advantages & Disadvantages of IBGP

Inter-Domain Border Gateway Protocol (IBGP) is a routing protocol used to exchange routing information across different Autonomous Systems (ASs).

It is widely used in today’s Internet and also plays a significant role in large enterprise networks.

IBGP offers many advantages over other routing protocols, such as increased scalability, improved security, and better control of routing information.

However, there are also some disadvantages associated with IBGP that must be taken into consideration before implementing the protocol.
