Why is EIGRP a distance vector protocol?

There is no doubt that it is a Distance Vector protocol, because it records only the distance to destinations – not the path (as OSPF and ISIS do). So the most correct way to describe EIGRP is indeed as an Advanced Distance Vector Routing Protocol.

Is EIGRP a distance vector or link state protocol?

EIGRP is a distance vector & Link State routing protocol that uses the diffusing update algorithm (DUAL) (based on work from SRI International) to improve the efficiency of the protocol and to help prevent calculation errors when attempting to determine the best path to a remote network.

Is OSPF a distance vector protocol?

OSPF is not a distance-vector protocol like RIP, but a link-state protocol with a set of metrics that can be used to reflect much more about a network than just the number of routers encountered between source and destination. In OSPF, a router attempts to route based on the “state of the links.”

Which protocol is a distance vector protocol?

Routing Information Protocol
RIP (Routing Information Protocol) is a distance vector routing protocol that uses hop count as its metric.

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.

Is distance a vector protocol?

A simple routing protocol that uses distance or hop count as its primary metric for determining the best forwarding path. RIP, IGRP and EIGRP are examples. A distance vector protocol routinely sends its neighboring routers copies of its routing tables to keep them up-to-date.

What is not a routed protocol that is supported by EIGRP?

Simple Network Management Protocol (SNMP) MIB is not supported. Interface static routes are not automatically redistributed into EIGRP, because there are no network commands. Metric configuration (either through the default-metric command or a route policy) is required for redistribution of connected and static routes.

Is RIPv2 a distance vector protocol?

We will examine the behavior of two distance vector routing protocols, Enhanced Interior Gateway Routing Protocol (EIGRP) and Routing Information Protocol version 2 (RIPv2).

Which is an example of distance vector protocol?

What is distance vector?

A distance-vector routing protocol in data networks determines the best route for data packets based on distance. The term distance vector refers to the fact that the protocol manipulates vectors (arrays) of distances to other nodes in the network.

How does EIGRP calculate advertised distance?

You add the bandwidth and the delay to reach 8,476 and multiply it by 256 which gives you 2169856. Now the Advertised Distance (AD) is the metric advertised from a neighboring router. For example, when viewing the EIGRP topology table on R1 the 172.16.

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.
