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

It is also a distance vector routing protocol. In this, Bellman ford algorithm is used. The least hop count in IGRP is 255….Difference between IGRP and EIGRP:

S.NO IGRP EIGRP
6. The least hop count in IGRP is 255. While the least hop count in EIGRP is 256.
7. It provides 24 bits for delay. While it provides 32 bits for delay.

How are EIGRP metrics calculated?

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.

How do you calculate EIGRP composite metric?

EIGRP Wide Metrics

  1. Metric = [(K1*Minimum Throughput + {K2*Minimum Throughput} / 256-Load) + (K3*Total Latency) + (K6*Extended Attributes)]* [K5/(K4 + Reliability)]
  2. Composite Cost Metric = (K1*Minimum Throughput) + (K3*Total Latency)
  3. Minimum Throughput = (107* 65536)/Bw), where 65536 is the wide-scale constant.

How do you calculate EIGRP metric and K values?

The formula we use for the metric calculation looks like this:

  1. Metric = [K1*bandwidth + ((K2*bandwidth)/(256-load))+K3*delay]
  2. Metric = Metric*[K5/(reliability+K4)]
  3. Metric = bandwidth (slowest link) + delay (sum of delays)
  4. Metric = (107 / minimum bandwidth) * 256 + (sum of delays) * 256.

What is Igrp protocol and how it works?

Interior Gateway Routing Protocol (IGRP) is a proprietary distance vector routing protocol used to communicate routing information within a host network. It was invented by Cisco. IGRP manages the flow of routing information within connected routers in the host network or autonomous system.

What is metric of EIGRP?

EIGRP Metric = 256*((K1*Bandwidth) + (K2*Bandwidth)/(256-Load) + K3*Delay)*(K5/(Reliability + K4))) By default, the values of K1 and K3 are set to 1, and K2, K4 and K5 are set to 0.

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 calculated metrics. Use cases.

What is EIGRP metric?

EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU. EIGRP uses Five different messages to communicate with its neighbor routers. EIGRP messages are Hello, Update, Query, Reply, and Acknowledgement.

What is composite metric?

Composite metrics let you define a new higher-level metric by specifying an arbitrary set of mathematical transformations to perform on a selection of native metrics you’re sending us. You “compose” a new higher-level metric using the native metrics you send us as inputs.

How does EIGRP calculate k value?

It’s important to understand where to find the EIGRP k values in the Cisco network devices. The command “show interfaces (interface name)” will provide the detail of all the K-values i.e. Bandwidth, Load, delay, Reliability and MTU.
