Which Two Categories Of Inner Gateway Protocols Are There?

Interior Gateway Protocols (IGP) are dynamic routing protocols used on internal networks, categorized into two major types: distance-vector and link-state. IGPs are divided into two categories based on the algorithms and methodology they learn about networks. They are limited to the border router and are used to route traffic within each separate network of an autonomous system (AS).

Interior gateway protocols (IGP) are designed for use within a single set of networks, either under a single management or closely connected. There are two types of IGP: distance vector routing and link state routing. The basic concept of link-state routing is that every node constructs a map of connectivity to the network in the form of a graph, showing which nodes are connected to which other nodes. Each node independently calculates the next best logical path from it to every possible destination in the network.

IGP and IGRP are often used interchangeably, but they are the same. Examples of distance vector routing protocols include Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP). RIP is an open standard, while IGP is a type of routing protocol used within an autonomous system (a network or group of networks under a single administrative domain).

In summary, interior gateway protocols are dynamic routing protocols used on internal networks, with two main categories: distance-vector and link-state. These protocols are used to route traffic within separate networks of an autonomous system, and their classification depends on the algorithms and methodologies used to learn about networks.

What are the two most important protocols?

The Transmission Control Protocol (TCP) and Internet Protocol (IP) are crucial for the internet, often written together as TCP/IP. TCP ensures data is sent reliably over the internet through software ports that separate data on the same computer. Ports can mean physical connections on a device or numbers indicating how data is handled when it reaches its destination. Port 80, for example, represents the well-known HTTP port. Understanding TCP works requires knowledge of ports, which can mean different things depending on the context. Ports can be physical connections on devices or specific protocols, such as HTTP.

Which are Layer 2 protocols?

Layer 2 protocols, also known as network L2 protocols, are communication protocols used by Layer 2 devices like network interface cards (NIC), switches, and multiport bridges to transfer data in a wide area network or between nodes in a local area network. These protocols are part of the Open Systems Interconnection (OSI) model, which separates a network into seven different layers based on their functionality. Layer 2 is responsible for error-free data transmission between devices in the same network.

Other data link layer protocols include ARCnet, Asynchronous Transfer Mode (ATM), Econet, Ethernet, EAPS, Fiber Distributed Data Interface (FDDI), Frame relay, and High-Level Data Link Control (HDLC).

What is the difference between IGP and EGP and BGP?

IGPs, such as EIGRP OSPF and IS-IS, route traffic within Autonomous Systems (AS). External Gateway Protocols (EGPs) are used to route traffic between ASs, with BGP being the only EGP in any production network and the Internet routing protocol. BGP has almost completely replaced the older legacy EGP protocol, also known as Exterior Gateway Protocol (EGP). Both the category of routing protocols and the legacy protocol have the same name.

What are the two types of interior gateway protocols?

Interior gateway protocols (IGP) are utilized for the purpose of routing data traffic within the confines of autonomous system (AS) networks. Two principal types of interior gateway protocol have been identified: distance vector routing and link state routing. The functionality of IGP permits users to modify a number of personal details, including usernames, passwords, addresses, purchase history, payment options, order history, document viewing, and personal information.

Which of the following are types of interior gateway protocols?

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 OSPF IGP or EGP?

In his text, “OCG ICND1 100-101,” Wendell Odom posits that the Open Shortest Path First (OSPF) protocol is an Interior Gateway Protocol (IGP), whereas only the Border Gateway Protocol (BGP) is an Exterior Gateway Protocol (EGP). This assertion is made on page 464 of the aforementioned text.

Why we use BGP instead of IGP?

IGP protocols calculate bandwidth using bandwidth and have few tools for path selection, allowing only outbound direction traffic manipulation. BGP, on the other hand, is used for service layer (overlay mechanism) and customer prefixes in Service Provider networks. BGP is multi-protocol technology, capable of carrying 20 different address families for various purposes such as IPv4 unicast, IPv4 multicast, IPv6 multicast, EVPN, L2VPN, security, quality of service, and multicast.

IGP protocols are typically used for IPv4 and IPv6 Unicast purposes, with a separate protocol called PIM used for multicast. This comparison is brief, as IGP vs BGP and OSPF vs EIGRP are discussed in detail in separate posts on the website.

What are the two protocol categories?

Network protocols are essential for various aspects of an organization, including communication, management, and security. Communication protocols like TCP/IP and HTTP are basic data communication tools, while management protocols like ICMP and SNMP govern the network. Security protocols like HTTPS, SFTP, and SSL are used for secure communication. The choice of protocol depends on the organization’s needs and size.

What are the categories of IGP protocols?

Interior gateway protocols, such as OSPF, RIP, IS-IS, and EIGRP, are used to exchange routing information between autonomous systems. Exterior gateway protocols, on the other hand, exchange routing information between autonomous systems and rely on IGPs to resolve routes within an autonomous system. Examples of IGPs include RIP, RIPv2, RIPng, IGRP, and Babel. These protocols are essential for efficient communication and routing within autonomous systems.
