What is feasibility distance?
Feasible Distance is the lowest distance to the destination experienced since the last time the route went from Active to Passive state.
How do you identify a feasible successor?
A successor route for any given destination is chosen as having the lowest computed feasible distance; that is, the lowest sum of reported distance plus the cost to get to the advertising router.
What is the EIGRP feasibility condition?
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 do you find the 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 feasible distance FD?
Feasible distance (FD) – the metric of the best route to reach a network. That route will be listed in the routing table. Reported distance (RD) – the metric advertised by a neighboring router for a specific route. It other words, it is the metric of the route used by the neighboring router to reach the network.
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 a feasible route?
Which is the best measure of feasible distance?
The Feasible Distance, or FD in short, is the historical minimum of the best metric towards that particular destination (with the history starting from scratch when the route neds to enter the Active state and then returns back to Passive state).
What’s the difference between reported and feasible distance?
Reported (advertised) distance (RD or AD) – the metric advertised by the neighboring router for a specific route. This is the metric of the route used by the neighboring router to reach that specific destionation network. Feasible distance (FD) – the local router’s metric of the best route to reach a specific network.
How is the feasible distance calculated on a router?
Feasible distance (FD) – the local router’s metric of the best route to reach a specific network. The metric is calculated using the metric reported by the neighbor (the advertised distance) plus the metric to the neighbor reporting the route. The route with the lowest FD will be placed in…
What’s the name of the metric for reported distance?
These metric have their own names: Reported (advertised) distance (RD or AD) – the metric advertised by the neighboring router for a specific route. This is the metric of the route used by the neighboring router to reach that specific destionation network.
