The third category of routing protocols is Advanced Distance Vector.

2

In theory, EIGRP or Enhanced Interior Gateway Protocol takes the best

3

of both distance vector and links state routing protocols and combines that

4

into a single routing protocol

5

You may see that EIGRP is described as a hybrid routing protocol

6

where it combines elements of both distance vector

7

and link state into a single routing protocol.

8

That isn't entirely true and in the EIGRP videos

9

we'll discuss that in a lot more detail.

10

In theory, EIGRP takes the best of distance vector and that is very easy to configure.

11

You could configure EIGRP on a router as an example

12

by using just 2 commands and thus it' very easy to configure

13

in the same way that RIP in the past was easier to configure.

14

EIGRP, however, forms neighbor relationship in a similar way

15

to link state routing protocols such as OSPF.

16

So unlike distance vector routing protocols like RIP

17

that do not form neighbor relationships.

18

EIGRP does form neighbor relationships.

19

So, in theory, it's taking best of both distance vector

20

and link state and combining them into a single routing protocol

21

that gives you the power of a link state routing protocol

22

with the ease of configuration of a distance vector routing protocol.

23

the disadvantage of EIGRP is that it's Cisco propriety

24

so unless you running a pure Cisco network

25

you may have to choose a different routing protocol

26

such as OSPF if however, all your devices are Cisco devices

27

EIGRP is a very good choice.

28

It’s very easy to configure

29

it’s very quite, it updates very quickly

30

and is a good choice for most enterprise networks that only have Cisco devices.
