how do you determine your Wan addresses in a network

[IamDanielJ]

Hello i am unsure what addresses i should use as my Wan 1,2,3 in the physical topology can anyone point me in a direction.

Hello,

if you are referring to the serial interfaces connecting the three routers, the last octets are given. Unless there is a specific requirement with regard to IP addressing, just make sure that IP addresses on both sides of each link are in the same subnet, e.g. the link between R2 and R3 could be configured as:

R2

interface Serial0/0/0

ip address 192.168.23.65 255.255.255.0

R3

interface Serial0/0/0

ip address 192.168.23.61 255.255.255.0

yes its the serial ports i am referring we need 3 Wan's but i am not sure how i should proceed to explain if i am being asked about the Wan's.

Hello,

I don't understand what you are asking. What do you need to explain ? IP addressing works as described in my example...

[IamDanielJ]

forget it thanks tho dont think i am getting anywhere with this.

I agree with George.  
What do you mean by "how i should proceed to explain if i am being asked about the Wan's"?  Ask by your professor/school instructor about what?

i think i might have messed up my subnet addresses what i want is all serial ports to be in the same subnet range without colliding together if that sounds correct.

Hey IamDanielJ, your last post with that topology makes sense. If I am correct, your looking to make 3 seperate subnets for each WAN?

Try the below!

WAN1

R1 - 192.168.72.113 /24

R2 - 192.168.72.114 /24

WAN2

R3 - 192.168.73.116 /24

R2 - 192.168.73.117 /24

WAN3

R1 - 192.168.74.122 /24

R3 - 192.168.74.121 /24

I hope this helps!
