So routed protocols include IPv4 and IPv6

2

these protocols are independent of each other

3

and to illustrate that let's look at a simple topology.

4

So here’s a question for you; Are these routers able to ping each other?

5

And the answer is yes and no

6

there’s a problem in the IPv4 addressing structure in this topology.

7

These 2 interfaces have IP addresses of 10.1.2.1/24 and 10.1.4.2/24

8

they are in different subnets but have been configured on the same link.

9

So router 1 and router 2 will not be able to ping each other using IPv4

10

however, IPv6 has been correctly configured

11

so these 2 addresses are in the same subnet

12

and router 1 and router 2 will be able to ping each other using IPv6.

13

The point is what 1 routed protocol does is totally independent and separate

14

from another routed protocol, routed protocols such as IPv4 and IPv6

15

act and work independently of each other and use different routing protocols

16

In the networking world, this is often called ships in the night

17

in other words, what 1 ship in the night is doing is different

18

to what another ship in a night is doing.

19

A routed protocols are independent of each other and do not rely on one another.

20

Routed protocols used different routing protocols

21

as an example, OSPF v2 is a routing protocol used in IPv4

22

OSPF v3 is routing protocol used in IPv6

23

Different routed protocols used different routing protocols

24

and they act independently of each other.

25

Even if 1 routed protocol is broken other routed protocols may still function.
