An interior gateway protocol (IGP) is a type of routing protocol used for exchanging routing table information between gateways within an autonomous system, such as corporate local area networks. IGPs are divided into two major types based on algorithms and are used to route traffic within each separate network of an autonomous system.
Interior gateway protocols (IGP) are essential for directing data packets within a single network. They are limited to the border router and are used within an organization’s network. External gateway protocols (EGP) are used to connect different networks.
There are two types of IGP: distance vector routing and link state routing. Distance vector routing gives each router in the network information, while link state routing uses the same routing information as the other two types. Examples of IGP include Open Shortest Path First (OSPF), Routing Information Protocol (RIP), Intermediate System to Intermediate System (IS-IS), and Enhanced Interior Gateway Routing Protocol (EIGRP).
The coordination between IGP and EGP is one of the most important aspects of routing protocols. The most popular IGP protocols include RIP2, which coordinates with EGP, and RIP, which provides information to each router in the network.
Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are examples of distance vector routing protocols. RIP is an open standard, while IGRP (Interior Gateway Routing Protocol) is a Cisco proprietary distance-vector routing protocol used in enterprise networks to exchange routing information.

What are the different types of IGP?
Internet gateways (IGPs) can be classified into two main categories: distance vector routing and link state routing. The platform enables users to modify a range of personal information, including usernames, passwords, addresses, purchase details, payment options, order history, document viewing, and profile information.
Is BGP an interior gateway protocol?
BGP is an exterior gateway protocol designed to share routing information between different ASes, while an interior gateway protocol sends information within a single AS. Internal BGP (iBGP) is available for reachability information within an organization’s network. Each router maintains a standard routing table for packet direction. BGP uses a client-server topology, with the client initiating a session by sending a request to the server. It sends updated router table information only when something changes, and network admins must manually set up connections between peers.
Is BGP an EGP?
The Exterior Gateway Protocol (EGP) was a routing protocol used from the mid-1980s to mid-1990s to connect autonomous systems on the Internet. It was developed by Bolt, Beranek, and Newman in the early 1980s and was first described in RFC 827 and formally specified in RFC 904. It was replaced by Border Gateway Protocol (BGP) in the mid-1990s. The EGP was a crucial protocol for connecting network systems and was a precursor to the modern Internet.
What is an example of an interior gateway protocol?
Interior gateway protocols can be categorized into distance-vector and link-state routing protocols. IGP protocols, such as OSPF, RIP, and IS-IS, are used to exchange routing information between autonomous systems. On the other hand, exterior gateway protocols exchange routing information between autonomous systems and rely on IGPs to resolve routes within an autonomous system. Distance-vector routing protocols use the Bellman-Ford algorithm, where each router advertises its distance value to other routers, receiving similar advertisements unless changes occur in the local network or by neighboring routers. This process continues until the routers’ routing tables converge to stable values.
Is EIGRP better or OSPF?
OSPF and EIGRP are two routing protocols that differ in their performance and resource requirements. OSPF requires network partitioning to scale better, while EIGRP does not. Both protocols converge faster than other BGP protocols, but EIGRP is faster due to an internal mechanism. OSPF uses interface bandwidth as a metric, while EIGRP uses a combination of parameters to calculate the metric. EIGRP supports unequal path load balancing, allowing better usage of links at different speeds for forwarding traffic simultaneously. Additionally, EIGRP allows summarization on any router on any interface, unlike OSPF, which only allows for specific router types.
What are the three types of gateways?
In the context of information technology, a unidirectional gateway is a system that permits the transmission of alerts in a single direction, whereas a bidirectional gateway is a system that allows for the bidirectional flow of alerts.
What is an example of a gateway protocol?
Gateways are essential components in network management, enabling organizations to manage traffic between different types of networks. They can take various forms, such as web application firewalls, cloud storage gateways, API, SOA, or XML gateways, IoT gateways, media gateways, email security gateways, and VoIP trunk gateways. These gateways filter traffic to and from web servers, integrate storage from a private cloud into applications, manage traffic flow, aggregate sensor data, convert data formats, prevent email transmission that violates company policy, and facilitate the use of telephone service equipment.
Service providers can also develop their own personal gateways for customers, such as Amazon Web Services’ API Gateway. These gateways allow developers to connect non-AWS applications to AWS back-end resources. However, a router is used to join two similar types of networks, while a gateway is used to join two dissimilar networks, which could be used to describe networks using different primary protocols.
Is OSPF an IGP?
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks, using a link state routing (LSR) algorithm. It belongs to the group of interior gateway protocols (IGPs) operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the network, which is presented as a routing table to the internet layer for routing packets by their destination IP address.
OSPF supports Internet Protocol version 4 (IPv4) and IPv6 networks and is widely used in large enterprise networks. OSPF version 2 was designed in the 1980s and was updated in 2008 for IPv6. It supports the Classless Inter-Domain Routing (CIDR) addressing model.
Which of the following is an example of interior gateway protocol?
Interior gateway protocols can be categorized into distance-vector and link-state routing protocols. IGP protocols, such as OSPF, RIP, and IS-IS, are used to exchange routing information between autonomous systems. On the other hand, exterior gateway protocols exchange routing information between autonomous systems and rely on IGPs to resolve routes within an autonomous system. Distance-vector routing protocols use the Bellman-Ford algorithm, where each router advertises its distance value to other routers, receiving similar advertisements unless changes occur in the local network or by neighboring routers. This process continues until the routers’ routing tables converge to stable values.
What is an example of an EGP?
External Gateway Protocols (EGPs) are protocols that allow multiple autonomous systems to communicate using an EGP. The Border Gateway Protocol (BGP) is the most popular EGP, as it allows devices connected to the internet to route between each other. Interior Gateway Protocols (IGPs) are used on an internal network, where the internal system is the autonomous system. Exterior gateway protocols handle specific functions, such as OSPF, ISIS, RIP, and EIGRP.
The Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco protocol for internal gateways. It is used internally for dynamic routing, while OSPF is used for external systems.
Companies with multiple autonomous systems use different protocols for dynamic routing, such as Company A using RIP internally, Company B using OSPF, Company C using EIGRP, and Company D using RIPv2. These protocols help manage and manage the communication between different autonomous systems in a network.
Is OSPF an interior gateway protocol?
The Open Shortest Path First (OSPF) protocol is a link-state routing protocol that ensures that routers or systems within the same area maintain an identical link-state database that describes the area’s topology.
