What is EIGRP feasible distance?

What is EIGRP feasible distance?

The Feasible Distance (FD) is the distance from the current router to the destination router. Feasibility Condition (Requirement) Within EIGRP there is requirement which must be met for a route to be considered feasible and loop-free.

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 metric for EIGRP?

EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU.

What is feasible condition in EIGRP?

The Feasibility Condition states that a route will not be accepted if the Reported Distance is more than the best path’s Feasible Distance. Or said another way and from the perspective of the router: a path to a network will not be accepted if my neighbor’s cost is more than my cost.

How does EIGRP determine feasible successor?

The FD for the successor route is 264416. If another route’s RD is less than the successor’s FD, it becomes the feasible successor.

What is K6 in EIGRP?

“5.4.4 Coefficients K6. K6 has been introduced with Wide Metric support and is used to allow for Extended Attributes, which can be used to reflect in a higher aggregate metric than those having lower energy usage. Currently there are two Extended Attributes, jitter and energy, defined in the scope of this document.”

What is the difference between feasible distance and advertised distance?

The advertised distance, your neighbor tells you how far it is for him to reach the destination and the feasible distance which is your total distance to get to the destination.

What is feasible successor?

A feasible successor is a backup route that can be used in the event of a topology change without having to recalculate routes. The feasible successor can be used instantly, which means convergence time is instantaneous.

What are the 5 K values in EIGRP?

To calculate the cost of a route, EIGRP uses a composite metric calculation formula. The formula can use five components in the calculation. These components are Bandwidth, Delay, Load, Reliability, and MTU.

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.

What is K value in routing?

These K values are only numbers to scale numbers in the metric calculation. The formula we use for the metric calculation looks like this: Metric = [K1*bandwidth + ((K2*bandwidth)/(256-load))+K3*delay] If K5 is not equal to 0: Metric = Metric*[K5/(reliability+K4)]

How metric is calculated in EIGRP OSPF RIP?

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.

What is metric value?

A metric is a value that’s assigned to an IP route for a particular network interface. It identifies the cost that’s associated with using that route. For example, the metric can be valued in terms of link speed, hop count, or time delay.

What is metric and administrative distance?

The difference between administrative distance and metric is that AD is used to choose between multiple paths learned via different routing protocols. Metric, on the other hand, is used to choose between multiple paths learned with the same routing protocol.
