IS-IS

Intermediate System to Intermediate System (IS-IS) is a link-state routing protocol used in computer networks to determine the best paths for data packet forwarding within a single autonomous system (AS). Similar to OSPF (Open Shortest Path First), IS-IS is designed for interior gateway routing and is commonly used within large and complex networks, including Internet […]

OSPF

Open Shortest Path First (OSPF) is a widely used and standardized link-state routing protocol for determining the best paths for data packet forwarding within a single autonomous system (AS) in computer networks. OSPF is commonly used in enterprise and service provider networks due to its scalability, flexibility, and robustness. Key characteristics and aspects of OSPF

EIGRP

Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced and proprietary routing protocol developed for use within autonomous systems (ASes) in computer networks. EIGRP is designed to facilitate the exchange of routing information and determine the best paths for data packet forwarding within a single autonomous system. Key characteristics of EIGRP include: EIGRP is widely

IGRP

Interior Gateway Routing Protocol (IGRP) is a distance-vector routing protocol developed by Cisco Systems for use within autonomous systems (ASes) in computer networks. It is designed to facilitate the exchange of routing information and the determination of the best paths for data packet forwarding within a single autonomous system. Key characteristics of IGRP included: It’s

Exterior Gateway Protocol (EGP)

Exterior Gateway Protocol (EGP) is a type of routing protocol used to exchange routing information between different autonomous systems (ASes) in a network. Unlike Interior Gateway Protocols (IGPs), which focus on routing within a single AS, EGP is designed to facilitate routing between separate administrative domains. The primary purpose of EGP is to enable routers

Interior Gateway Protocol (IGP)

Interior Gateway Protocols (IGPs) are a type of routing protocol used within a single autonomous system (AS) in a computer network. An autonomous system is a collection of IP networks and routers under a single administrative domain. IGPs are responsible for determining the best paths for routing data packets within the boundaries of the same

BGP

BGP (Border Gateway Protocol) is a standardized routing protocol used in computer networks to exchange routing and reachability information between autonomous systems (ASes). An autonomous system is a collection of IP networks and routers under a single administrative entity. BGP plays a crucial role in the functioning of the internet, as it helps determine the

EVPN

EVPN (Ethernet Virtual Private Network) is a network technology that provides a flexible and efficient way to connect geographically dispersed sites within a data center or across wide area networks (WANs). EVPN uses the BGP (Border Gateway Protocol) control plane to enable the creation of virtual networks that support multi-tenancy, layer 2 and layer 3

IP

IP stands for Internet Protocol, and it is one of the most important technologies used in today’s networks. IP is the communication protocol used to transmit data between devices on a network. It is used by almost all modern computer networks, including the Internet. The IP protocol provides a unique address to each device on

ARP

ARP stands for Address Resolution Protocol. It is a protocol used to map a network address, such as an IP address, to a physical (MAC) address on a local network. For instance, When a device on a network wants to communicate with another device, it needs to know the other device’s MAC address. ARP allows
