A composite measurement is a number determined in light of a few unique parts that decide the favored course. Naturally, EIGRP utilizes data transfer capacity and defer to ascertain the favored way to an organization. The dependability and load can likewise be utilized, however are not suggested, in light of the fact that they regularly bring about a continuous recalculation of the geography table.
Transmission capacity: The transfer speed esteem utilized in the EIGRP not set in stone by isolating 10,000,000 by the transfer speed (in kbps) of the slowest cordial connection point along the way from the source to the objective organization.
Delay: It is the aggregate worth of all postponements related with every one of the connection points along the way from the source to the objective (in many microseconds). We can show the postponement in the result of the show interfaces order.
Unwavering quality: It is the most awful dependability between the source and objective in light of keep alive.
Load – Represents the most awful burden on a connection between the source and objective, decided in view of the bundle rate and the arranged transfer speed of the point of interaction.
Figure 1 outlines the EIGRP composite metric recipe.
The recipe comprises of K1 to K5 values, known as EIGRP metric loads. K1 transfer speed, K3 address delay, K2 addresses burden, and K4 and K5 address unwavering quality. The data transfer capacity and defer values are utilized in the default composite measurement. EIGRP for IPv4 and EIGRP for IPv6 both utilize a similar equation for the composite measurement. K1 and K3 values are set to 1 in the default recipe, K2, K4 and K5 are set to 0.
The metric estimation strategy (k qualities) and the independent framework number of the EIGRP should match between neighbors; any other way, switches don’t play out a contiguousness. The order for changing the default k qualities is “metric loads” switch setup mode order. The order punctuation is as under:
Router(config-router)# metric loads
TOS represents the Type of Service Byte in an IPv4 bundle header. It is planned to be utilized for a nature of administration checking. However, the worth of TOS should be 0. The five k qualities can be set into the reach between 0 – 255. The measurement loads esteem should be no different for laying out neighbor adjacencies. In the event that measurement loads values are unique, nearness doesn’t frame.
Confirming the k Values
We can confirm the k qualities utilizing the “show ip conventions” order. Figure 2 shows the result of this order for R1. The k qualities on R1 are set to the default.
Analyzing Interface Values
We can analyze the qualities utilized in the metric estimation utilizing the “show interfaces” order. The order additionally shows total connection point data. Figure 3 represents the show interfaces order yield for the Serial 0/0/0 point of interaction on R1. The boundaries utilized in the metric estimation recipe are set apart with a red square shape.
BW-This is the connection point transfer speed. The transfer speed is in kilobits each second.
DLY-This is the deferral of the connection point. The deferral is in microseconds.
Dependability The unwavering quality of the connection point is a small portion of 255. Assuming the worth is 255/255, it implies that the dependability is 100 percent. The unwavering quality is determined as a remarkable normal more than five minutes.
Txload, Rxload-This is sent and get load on the point of interaction as a negligible portion of 255 yet 255/255 is totally soaked. The worth is determined as a dramatic normal north of five minutes.
MTU – The MTU (Maximum Transmission Unit) isn’t utilized in the metric estimation recipe. The default worth of the Maximum Transmission Unit is 1500 Bytes. The Maximum Transmission Unit is conveyed in the EIGRP Update message to be utilized when tie happened.
