My networking assignment

For a VLSM class B, would this be ok?

Admin (48 PC's)
IP:172.16.0.65
Subnet Mask:255.255.255.192

Sales (48 PC's)
IP: 172.16.0.129
Subnet Mask: 255.255.255.192

Warehouse (62 PC's)
IP: 192.16.0.195
Subnet Mask: 255.255.255.192

Server 1
IP: 172.20.1.6
Subnet Mask: 255.255.255.252

Server 2
IP: 172.20.1.5
Subnet Mask: 255.255.255.252

Serial Link
IP 172.16.1.4 - 172.16.1.3
Subnet Mask: 255.255.255.252

Is this Correct? ty for any replys

The Admin, Sales and Warehouse are all correct. But the two servers are not. Why? because you will need a 3rd IP for the Router 2 interface facing the Switch 40. So 255.255.255.252 is not enough as a subnet mask. Try 255.255.255.248. You could also use a higher subnet mask for simplicity. It's NOT always a must to choose the BEST FIT mask unless you want to reserve the address range, it depends on the question you have. For example you can use a mask 255.255.255.0 for all the subnets Admin, Sales and Warehouse and the two servers. And make the changes only in the 3rd octet, like 192.168.1.0, 192.168.2.0, 192.168.3.0 and so on. This will make binary work simple.

For the serial link 172.16.1.4 - 172.16.1.3. The subnet mask 255.255.255.252 is OK. But the two IPs are on a different subnet since the 4 bit on the last octet is different in each IP. Try some thing like 172.16.1.9 - 172.16.1.10.

Remember that you also have another serial link in the network.

Class B VLSM

My idea is to restrict the number of hosts per network therefore there is more physical security I could also limit the ip addresses the dhcp server gives out so, however when computers are shut down the ip's become free again one way to sort this could be dynamic ip mac filtering.

currently there is nice green lights but pinging just wont happen, I guess i will need to configure the v-lan,

in this image do I still need to configure the serial link or would this now be the gig ethernet ip and subnet instead?

Bump Any 1?

Could you post a link to your .pkt file? It will help us better understand your problem.

here is the link to the packet tracer file, theres a small button on that web site that say "Save file to your PC: click here" took me a while to find it lol

Thanks for Any help
