What are the two types of interior gateway protocols?

An interior gateway protocols (IGP) is used to route the traffic within each separate network of an autonomous system (AS). There are two types of IGP: distance vector routing and link state routing.

What is the main difference between EIGRP and Rip?

The main advantage of using RIP is it uses the UDP (User Datagram Protocol). 2. Enhanced Interior Gateway Protocol (EIGRP) : EIGRP stands for which allows router to share information to the neighboring routers which are within the same area.

What is the difference between OSPF and EIGRP?

Key Differences Between EIGRP and OSPF. EIGRP is an advanced distance vector routing protocol which uses incremental and triggered updates. On the other hand, OSPF is a link-state routing protocol which resembles a map where the complete information about all the routes within that area is maintained.

What is classless protocol?

Classless routing protocols do send the subnet mask with their updates. Thus, Variable Length Subnet Masks (VLSMs) are allowed when using classless routing protocols. Examples of classful routing protocols include RIPv1 and IGRP. Examples of classless routing protocols include RIPv2, EIGRP, OSPF, and IS-IS.

What is the difference between interior & exterior routing protocol?

Interior gateway protocols are used inside an organization’s network and are limited to the border router. Exterior gateway protocols are used to connect the different Autonomous Systems (ASs). Each router running an exterior routing protocol is actually keeping the ASs apart from each other.

Does OSPF use TCP or UDP?

OSPF Packets Because OSPF does not use UDP or TCP, the OSPF protocol is fairly elaborate and must reproduce many of the features of a transport protocol to move OSPF messages between routers.

Why we use OSPF?

The OSPF protocol is a link-state routing protocol, which means that the routers exchange topology information with their nearest neighbors. The main advantage of a link state routing protocol like OSPF is that the complete knowledge of topology allows routers to calculate routes that satisfy particular criteria.

What is the most common routing protocol?

OSPF
Among all the three chosen samples, OSPF is the most widely used routing protocol in large enterprise networks. OSPF is based on link-state technology by using SPF algorithm which calculates the shortest path.

Should I use OSPF or EIGRP?

EIGRP is a popular choice for routing within small and big campus networks. While OSPF is the best choice when your network hardware devices come from various vendors.

What is EIGRP ( enhanced interior gateway routing protocol )?

EIGRP (Enhanced Interior Gateway Routing Protocol) is a network protocol that lets router s exchange information more efficiently than with earlier network protocols. EIGRP evolved from IGRP (Interior Gateway Routing Protocol) and routers using either EIGRP and IGRP can interoperate because…

Which is the most used dynamic routing protocol?

EIGRP Protocol is one of the most used Dynamic Routing Protocol as IGP (Interior Gateway Protocol). Especially it is used for Routing purpose inside the networks that is mostly consist of Cisco devices.

What is the enhanced distance vector protocol ( EIGRP )?

EIGRP is an enhanced distance vector protocol, relying on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a destination within a network. Major Revisions of the Protocol There are two major revisions of EIGRP, versions 0 and 1.

How does EIGRP and IGRP interoperate with each other?

EIGRP evolved from IGRP (Interior Gateway Routing Protocol) and routers using either EIGRP and IGRP can interoperate because the metric (criteria used for selecting a route) used with one protocol can be translated into the metrics of the other protocol.
