Easy to Understand Enhanced Interface Gateway Routing Protocol | EIGRP Explained


Enhanced Interface Gateway Routing Protocol  (EIGRP)


Enhanced Interface Gateway Routing Protocol (EIGRP) EIGRP Explained is an advanced range vector routing protocol. This protocol is the development of an earlier Cisco protocol called IGRP, which is now considered outdated. EIGRP supports classless routing and VLSM, route synthesis, incremental updates, load balancing and many other useful features. This is a Cisco proprietary protocol. All routers on a network running the EIGRP protocol must be Cisco routers.


Routers who run EIGRP must be neighbors before changing route information. To dynamically identify neighbors, EIGRP routers use the 224.0.0.10 multicast address. Each EIGRP router stores routing and topology information in three tables:

The neighboring table - stores information about neighbors in the EIGRP

Topology table - stores routing information acquired by nearby routers

Routing Table - stores the best roads




The administrative distance to the EIGRP protocol is 90, which is less than both the administrative distance from the RIP protocol and the administrative distance to the OSPF protocol. As a result, EIGRP stretches will be preferred over these roads. EIGRP uses a trusted transport protocol (RTP) to send messages.

EIGRP calculates its metrics by bandwidth, delay, reliability and load. By default, only bandwidth and delay in calculation are used, while reliability and load are set to zero.



EIGPR uses the concept of autonomous systems. An autonomous system is a set of EIGRP-enabled routers that will be EIGRP neighbours. Each router in an autonomous system must have the same autonomous system number configured, otherwise the routers will not be neighbours.

Neighbours EIGRP

The EIGRP protocol must establish neighbouring relationships with other routers adjacent to the EIGRP protocol prior to exchange of routing information. To create neighbouring relations, the routers send hello packages every couple of seconds. Hello package is sent to the multicast address at 224.0.0.10.

NOTE
On LAN Interface, Hellos is sent every 5 seconds. On WAN Interface every 60 seconds.


The following fields in a hatchet must be identical to the routers to be neighbours:

ASN (Autonomous System Number)
subset number
K-values ​​(components in metric)


Routers send hello packages every two seconds to ensure that the neighbourhood relationship is still active. By default, routers consider the neighbour to be in use after the end of a waiting hour. By default, the retention timer is three times the hay interval. On LAN, waiting time is 15 seconds.

Feasible and reported distance

Two terms that you will often encounter when working with EIGRP are achievable and reported distances. Clarify these terms:

Realistic Distance (FD) - Metric of the best way to reach a network. This route will be entered in the route table.

Declared Distance (RD): Metric published by a nearby router for a specific route. In other words, the metric route that the nearby router uses to reach the network.


To better understand the concept, consider the following examples.

reported achievable distance

The EIGRP protocol has been configured on R1 and R2. R2 is directly connected to the 10.0.1.0/24 subnet and announces this subnet in the EIGRP protocol. Assume that metric R2 to reach this subnet is 28160. When the subnet is advertised to R1, R2 informs its metric to reach 10.0.1.0/24 is 10. From R1, this metric is considered to be the distance reported for this route. R1 receives the update and adds the metrology to the neighbor at the reported distance. This measured value is called the achievable distance and is stored in the routing table of R1 (30720 in our case).

The possible and specified distances are shown in the EIGRP topology table of R1:

to display the topology feature of IP

Successor and successor achievable

Two other terms that often occur in the EIGRP world are successors and potential successors. A successor is the road with the best metric to reach a destination. This route is stored in the route table. Any successor is a backup path to reach the same destination, useful immediately if the tracker's route fails. These backup boxes are stored in the topology table.

In order for a route to be chosen as a possible successor, a condition must be met:

The advertised route (AD) for the neighbour of the route must be less than the successor's distance (FD).


The following example explains the term successor and achievable successor.

successors and successors that can be achieved.

EIGRP Explained Summary 

Here is a list of the most important features of the EIGRP:

*Advanced distance vector routing protocol

*Classless routing protocols

*Supports VLSM (variable length subnet mask)

*converged quickly

*Supports multiple protocols for network storage (IPv4, IPv6, IPX, AppleTalk ...)

*Uses the multicast address of 224.0.0.10 for routing updates

*Sends partial routing updates

*Supports load balancing at equal and uneven costs

*Supports manual synthesis on any router within a network

*By default, bandwidth and delay use to calculate its measurement value
  Cisco property

*Supports MD5 authentication

Routing Information Protocol (RIP) Interview Questions

Routing Information Protocol (RIP Protocol) is one of the oldest remote vector routing protocols. It is usually used on small networks, because it is very easy to configure and manage, but it lacks some advanced features in routing protocols such as OSPF or EIGRP. There are two versions of protocol version 1 and 2. Both versions use hop counts as a measure and have an administrative distance of 120. RIP version 2 can announce network masks and uses multicast to send routing update bets. while Version 1 does not publish subnet masks and uses are sent for updates. Version 2 is backward compatible with version 1.

Expert Level Certification
Cisco Certified Internetwork Expert is Cisco's highest certification, which currently consists of seven wires. Tracks are regularly updated and removed, and adapted to the latest technologies and industry trends. As of October 6, 2010, 25,810 persons had an active CCIE certification [40] [41] [42]. CertMag, [43] has voted the most technologically advanced computer certification and the statistics generally describe it as the highest paid certification in computer payroll studies.

The CCIE began in 1993 [44], originally a two-day laboratory, which was later replaced by a daily format. Less than 3% of Cisco-certified individuals earn CCIE certification and spend an average of thousands of dollars and 18 months of study before they succeed. [45] Many candidates build training laboratories at home using their old equipment and then sell to other candidates after they have passed. Alternatively, candidates can rent "rack time" online. CCIE contains a written exam and a "lab" exam (in each track). The written exam is a prerequisite for the lab degree and costs $ 400 per try. The written exam contains 100 questions that must be completed within 2 hours. After an approved written exam, the candidate has 18 months to pass the laboratory examination. The candidate has three years after passing the written exam to pass the laboratory. The lab is an eight-hour practical exam designed to show that the candidate is familiar with the theory of network interconnection and demonstrates advanced mastery. Candidates who do not pass the CCIE laboratory within this range must return the written exam before attempting to try the CCIE again. Minimum waiting time between attempts is one month.

Starting July 2014, the CCIE lab costs $1600 per try and 10 Cisco websites offer it all over the world. Some of these sites do not offer all CCIE tracks. According to a Cisco survey, $9050 represents the average cost of preparation for CCIE certification beginning in April 2006, mainly spent on the purchase of training equipment and teaching materials. [46] There are currently no formal prerequisites for the CCIE written exam, but Cisco recommends at least 3 to 5 years of network experience. CCIE is available as the first Cisco Certified Certification and no other certification was previously available. Associated and Professional Certifications have acknowledged the fact that CCIE exaggerates many network employees. Cisco has chosen not to subordinate lower level certifications to CCIE certification.

One can have the knowledge of holding several CCIE certifications. As of September 9, 2008, 1,729 people had multiple CCIE certifications. Of these, 274 have at least three CCIE certifications. [47] Adam McCombs described this qualification as "mainly a doctorate on the Internet" in season 1, episode 10 by Shark Tank.
After passing the laboratory test, Cisco assigns a CCIE number to a new CCIE. The first assigned CCIE century (1993) started at 1,024 and then increased. From August 2011, the highest number of CCIE was over 30,000. The first number assigned to the first place of the CCIE laboratory, rather than an individual, was in the form of a plaque at the entrance. by the laboratory. The assigned number 1025 to Stuart Biggs, who created the first written exam and the first lab exam. The first person who passed both CCIE's written examinations and laboratory tests, known as Terry Slattery [48], was consulted at Cisco early in the development of the lab. Slattery organized the first CCIE that did not work for Cisco. [49] [50] Each CCIE retains its number regardless of the number of certifications it receives. Every two years, a CCIE must pass a written exam to maintain certification. If this is not done, the certificate is suspended. After one year without passing, the certificate will be revoked. We can be then find the certification only from the beginning. Re certification can take place up to 2 years before expiration date. After certification / re certification, a CCIE must wait 6 months before it is again certified.

CCIE laboratory examinations are only administered in special laboratories for laboratory centers around the world. However, all test tracks are not available in a laboratory. [51]

Racc
Cisco Certified Architect Certification (CCAR) assesses the experience and skills of network designers who can support the increasingly complex networks of global organizations and effectively translate business strategies into technical strategies. [52] [53]

Cisco Certified Architect certification is administered as a board review. Candidates propose and defend an architecture solution that meets a set of business needs. Candidates are invited to change their proposals "on the fly", according to the additional requirements that the jury presents. Prerequisites include a CCDE certification, approximately 10 years of industry experience and approval of the program through an application.

Responsibility for Cisco Certified Architect:


Creation and development of corporate architecture
Analyzing technology and industry market development
Establish guiding principles for corporate networks
Choice of technology and products
Identification of the organization's resource needs
Lead the development of communication and education plans for corporate network architecture
CCIE Routing and Switching
Routing and switching seems to be the most popular track with 35,272 globally certified from May 18, 2012. [54] Certification includes a series of network concepts and protocols.

CCDE

CESF operates in line with the more established CCIE program and offers in some areas a higher skill than CCIE. Specifically, CESC identifies network professionals with specialized network design capabilities. The network design translates the company's needs into an end-to-end network design and an approach based on network expansion and integration solutions. [55] CCDE focuses on network architecture and does not cover implementation and operations. CCDE offers a supplier-independent curriculum that tests the company's analysis, design, planning and validation. [56] The course was created because employers needed a way to identify experienced network designers and architects who can handle all aspects of existing and new networking technologies and trends. [57] Although engineers (including many CCIEs) have met this role, certification has not developed in addition to CCDP certification. CESC numbering takes a different format than CCIE and is divided into one year and one number during that year. It uses the same CCIE tool to check qualified status. CCDE-certified individuals can use the CCIE Qualification Exam to certify and vice versa. CCDE provides basic principles and advanced network infrastructure principles for large networks. A CESF can demonstrate its ability to develop solutions that address planning, design, integration, optimization, operation, security and ongoing infrastructure-based support.

CCIE collabration

The voice track covers advanced topics in areas such as Service Quality, MGCP, Call Manager (Cisco VoIP PBX), Cisco Unity Connection (Cisco Voicemail Platform), Device Express, Unified Express Contact Center, Cisco Unified Presence Server, Cisco HWIC Server. 4ESW and 3750-24PS. As of September 9, 2008, only 802 CCIE Voice Certified Engineers held certificates. Most candidates succeed after three or four attempts in the laboratory, but some have required more than six. Many felt that the laboratory tests seemed as much a test of time management and planning as technical competence. The widely used platforms distinguish the voice lab test from other CCIE laboratory tests. You must perform configurations in the Windows 2003 Server environment, a Web CallManager GUI, and the IOS command line. As such, there are many adjustments between the many platforms.

In May 2013, Cisco announced that it would remove the CCIE Voice track and introduce the new CCIE Collaboration track, which included new topics like virtualization, Jabber instant messaging and video. After protesting against current and future proprietors of CCIE Voice, claiming that the differences were still insufficient to justify abandoning the track without the ability to switch to the new track, Cisco proposed a crossing road for voters existing. The cooperation Written exam may be available from 21 November 2013. The lab survey will be transferred from Voice to Collaboration on 14 February 2014.

CCIE Data Center

Cisco announced its availability in September of a CCIE Data Center Certification [58], which certifies the skill levels required to plan, prepare, power, monitor and troubleshoot complex data centers. The CCIE Data Center written exam will be available on September 3, 2012 [59]; The laboratory examination will be available in October [60].

CCIE Security

The security track covers advanced topics in areas such as ASA, FirePower, IOS Security, Wireless Security, Content Protection, Malware Protection, and more.

CCIE Service Provider

The Cisco CCIE Service Provider (CCIE) certification validates the expertise required by a network engineer to configure, create, troubleshoot and optimize an NGN complex and high-availability spatial infrastructure. Service Provider's IP. Candidates who prepare CCIE SP certification have in-depth knowledge of basic IP, aggregation / edge and remote access technology, stored 2 and 3 VPN, and managed services over an IP core network. 




Wireless CCIE

Candidates passing the CCIE Wireless certification degree show broad theoretical knowledge of wireless network and a solid understanding of Cisco WLAN technology (WLAN).

Specialist Certifications

In addition to the many certifications listed above, Cisco provides specialized certifications. [61]
Investigations for these certifications often focus on a specific technology and are generally intended for members of the Cisco Partner Program, including those who sell, design, or support Cisco products and services. By combining different exams, a Cisco partner can earn specialist status and benefit from additional benefits.

Specializations can be organized at the express, advanced and master level, reflecting the depth of partner skills in some technologies and architectures, and can be organized in a technology portfolio or architecture. The specializations are:

Business: Business Value Practitioner, Business Value Specialist in Enterprise Architecture, Business Architecture Practitioner
Enterprise Computer Specialist
cooperation
Datacenter
Internet of things
operating System Software
security
Service provider
