What is the difference between reported distance 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.
What is reporting distance?
Reported Distance is the metric/value between the destination and the first hop next to the source. Yes, or in other words, the Reported Distance, or RD, as advertised by a particular neighbor, is its current total distance to a particular destination. It is simply the neighbor’s own distance to the destination.
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 do you calculate feasible distance and advertised distance in EIGRP?
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.
How many feasible successors are there in EIGRP?
We can tell from this output that there is only one successor route, through R5 (with a feasible distance of 3072), but the secondary route through R4 is being held as a feasible successor.
What is the difference between distance vector and link state routing protocols?
In distance vector routing the routers receive the topological information from the neighbour point of view. On the contrary, in link state routing the router receive complete information on the network topology. Distance vector routing calculates the best route based on the distance (fewest number of hops).
What is administrative distance of EIGRP?
This is because EIGRP routes have (by default) the administrative distance of 90, while RIP route have a higher administrative distance of 120.
What is the difference between EIGRP and Rip?
In Routing Information protocol (RIP), the maximum number of Hop is 15, because it prevents routing loops from source to destination….Difference between RIP and EIGRP :
| SR.NO | RIP | EIGRP |
|---|---|---|
| 6. | It allow maximum hop count upto 15. | It allow maximum hop count upto 255. |
| 7. | It’s administrative distance is 120. | It’s administrative distance is 90. |
Which routing protocol is best between OSPF and EIGRP?
Both of them could be widely deployed in Internet Protocol (IP) networks for data communication. EIGRP is a popular choice for routing within small and big campus networks. While OSPF is the best choice when your network hardware devices come from various vendors.
What are feasible and reported distance in EIGRP?
Two terms that you will often encounter when working with EIGRP are feasible and reported distance. Let’s clarify these terms: Feasible distance (FD) – the metric of the best route to reach a network. That route will be listed in the routing table.
What is a feasible successor route in EIGRP?
A route is entered into the EIGRP topology table as a feasible successor only if it meets the feasibility condition, which asserts that the reported distance of a route must be lower than the feasible distance of the current successor route. To better illustrate this concept, consider the following scenario.
What is feasible distance (FD) and reported distance (Rd)?
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.
How does EIGRP router work?
By default, an EIGRP router will store only the route with the best (lowest) feasible distance in the routing table (or, multiple routes with equivalent feasible distances). However, under certain conditions, EIGRP will also maintain less-than-optimal routes in its topology table.
