VLSM Help

[JennisJennis]

Hello, I would like some help for this VLSM subnetting. Classless subnetting I still haven't gotten down yet, but classful is easy enough since you use the same sub mask.

So it gives me an IP: 192.168.1.0/24

and it gives me 2 hosts: Router 2: 30 hosts and Router 1: 14 hosts but it doesn't mention how many hosts the wan has or the switch etc.

from these info I have to somehow find out the ip addresses in packet tracer so i can connect the different routers/pcs/switches/wan and on paper I have to write down the subnet nr, network ID, Custom netmask, broadcast

here is the assignment: https://assignment.itslearning.com/Annotations/AnnotationApp.aspx?AnnotationAccessArea=1&AnnotationOfUserId=0&IsReadOnly=True&LearningObjectId=312684248&LearningObjectInstanceId=445241713&MobileBrowser=NotDefined&SourceUniqueId=08ee56c9-381b-47ce-a10...

and i've linked my packet tracer too. I really need help with this. Ps. I'm on 73% but I don't know how to get the 100%. I don't know if my RIP network is correct or my other ip addresses. Can someone take a look and help? It would be much appreciated

The line console code is classcon

the enable password is cisco

line vty code is classvty

Hello,

what are the router passwords ?

I think you posted this same lab and question before ?

Here is the correct IP addressing. Change the subnet masks on the PCs accordingly.

R1

interface GigabitEthernet0/0
ip address 192.168.1.33 255.255.255.240
duplex auto
speed auto
!
interface GigabitEthernet0/1
no ip address
duplex auto
speed auto
shutdown
!
interface Serial0/0/0
ip address 192.168.1.66 255.255.255.252
clock rate 2000000

R2

interface GigabitEthernet0/0
ip address 192.168.1.1 255.255.255.224
duplex auto
speed auto
!
interface GigabitEthernet0/1
no ip address
duplex auto
speed auto
shutdown
!
interface Serial0/0/0
ip address 192.168.1.65 255.255.255.252
clock rate 2000000

looked like i had the wrong subnet masks for my interface serials but even with those corrected I still only have 80% done. I've written all the other ip's you've sent and changed the pc's accordingly. What else do I need? I've provided the codes in one of my replies @Georg Pauwen @paul driver Also, paul, this is not like the previous assignment. This is classless instead of classful

Hello,

the IP configuration of your PCs is locked, which means your instructor has locked it. The LAN of R1 requires a /28 mask, the PC has a /27 mask. There is a mistake in the instructions, I would suggest to get with your instructor, as you cannot resolve this misconfiguration yourself.

[JennisJennis]

yes... Because you have to do it from the desktop @Georg Pauwen not from config but from desktop and then on ip configuration

Hello
I created the attached sometime back - review it and see if it helps you

I cannot gain accces to you PT file however-

rtr1-rtr2 - 192.168.1.0/30 = 2 hosts
rtr1 - 192.168.1.16/28 = 14 hosts
rtr2 - 192.168.1.32/27 = 30 hosts
