How the metric is calculated in EIGRP?

Bandwidth: The bandwidth value used in the EIGRP metric calculation is determined by dividing 10,000,000 by the bandwidth (in kbps) of the slowest link along the path to the destination network. Delay: Unlike bandwidth, which represents the “weakest link,” the delay value is cumulative.

What metrics does EIGRP composite metric use?

The Composite Metric The formula consists of values K1 to K5, known as EIGRP metric weights. K1 and K3 represent bandwidth and delay, respectively. K2 represents load, and K4 and K5 represent reliability. By default, K1 and K3 are set to 1, and K2, K4, and K5 are set to 0.

Does EIGRP support secondary addresses?

Cisco explicitly mentions that a secondary IP address is not used in the EIGRP hello packets, therefore EIGRP neighbors will not become adjacent using secondary IP addresses.

What is metric calculation?

Calculated Metrics are user-defined metrics that are computed from existing metrics and drive more relevant analyses and enable greater actionability without leaving the product. In this article: Creating calculated metrics. Using the Formula field and input examples. Using calculated metrics.

Which bandwidth value is used when calculating the EIGRP metric of a route?

Which bandwidth value is used when calculating the EIGRP metric of a route? The bandwidth factor that is used to calculate the composite metric of the EIGRP is defined as the slowest bandwidth of all outgoing interfaces between the source and destination.

How do you calculate administrative distance?

You can display the administrative distance of all routes on your router by typing the show ip route command:

  1. In the case above, the router has only a single route in its routing table learned from a dynamic routing protocols – the EIGRP route.
  2. Metric.
  3. RIP has been configured on all routers.

How does EIGRP calculate feasible distance?

feasible distance: Best metric among all path to a network. It is calculated by adding the advertised/reported distance advertised by the neighbor and the cost calculated by that current router to reach the neighbor. successor: It is the (lowest) best path to reach to any specific destination network.

What is the difference in metric calculation between EIGRP and IGRP?

The main difference between the IGRP and EIGRP is that, Interior Gateway Routing Protocol is Classful routing technique, while Enhanced Interior Gateway Routing Protocol is a classless routing technique. 1. IGRP stands for Interior Gateway Routing Protocol. EIGRP stands for Enhanced Interior Gateway Routing Protocol.

What is the maximum hop count for EIGRP?

Similar to its predecessor IGRP, EIGRP has a maximum hop count of 224 and a default maximum hop count of 100. EIGRP has administrative distance of 90.

How do you calculate network metrics?

EIGRP Metric = 256*(Bandwidth + Delay) Bandwidth = 10000000/bandwidth(i), where bandwidth(i) is the least bandwidth of all outgoing interfaces on the route to the destination network represented in kilobits. destination network, in tens of microseconds.

How to calculate the EIGRP metric value?

Enhanced Interior Gateway Routing Protocol (EIGRP) consider the following network performance related attributes to calculate the EIGRP metric value. 1) Bandwidth 2) Delay 3) Reliability and 4) Load EIGRP Metric = 256* ( (K1*Bandwidth) + (K2*Bandwidth)/ (256-Load) + K3*Delay)* (K5/ (Reliability + K4)))

What is the bandwidth and delay ratio for EIGRP?

If you wish to consider Bandwidth and Delay in a 2:3 ratio, you can set K1 to 2, and K3 to 3. This is what gives EIGRP such flexibility in its cost comparison, you can choose which attributes and how important each attribute is to your routing domain.

How often does EIGRP update load and reliability?

First, EIGRP does not do periodic updates — only triggered updates. As a result, the values for Load and Reliability are calculated once when a route is first learned, but are not updated dynamically as an interface becomes more or less saturated. A change in Load/Reliability does not trigger a new EIGRP update.

What is the EIGRP routing protocol?

EIGRP is a Cisco Proprietary routing protocol created in the 1980s. As such, Cisco was the only vendor that had the rights to implement said protocol. Until 1998 when Cisco released the specification as an IETF draft. One of EIGRP’s main benefits is being able to consider many different attributes when calculating a route’s cost, or metric.
