Building a Network for an office in Packet Tracer

In this exercise we had to do something different. A picture of a network was given to us.

The network has got the IPv4 network address 123.23.45.0/24 and the IPv6 network address 2a02:3eb:48::/48.

There are more servers, PCs and Laptops in the network but only a few of them have to be configured.

Start of by buliding a network similar to the ine above in Packet Tracer. The router are connected via the Serial connection. 

To make the laptops able to connect to the wireless access point you have to change the network card to the WPC300N and set the same ssid on the access point and on the soon to be connected laptops. Now the network is set up but you are not yet able to ping anything. The devices still have to be configured. 

Because we have five subnets (network A, B, C, D and the connection between the two routers) with different numbers of hosts we have to do VLSM for the IPv4 network. 

 

Router: 2 hosts - 2bit - 123.23.45.216/30 - 2a02:3eb:48:5::/64

Network A: 6 hosts - 3bit - 123.23.45.208/29 - 2a02:3eb:48:4::/64

Network B: 11 hosts - 4bit - 123.23.45.192/28 - 2a02:3eb:48:3::/64

Network C: 35 hosts - 6bit - 123.23.45.128/26 - 2a02:3eb:48:2::/64

Network D: 67 hosts - 7bit -123.23.45.0/25 - 2a02:3eb:48:1::/64

Now the interfaces on the routers have to be configured with the IP address from above. Don't forget to write router(config)#ipv6 unicast-routing.

Configuring all the IP-addresses for the hosts is a lot of work we don't have to do. We can use a DHCP server so it does our work. 

 

Now go to the IP configuration of one of the PCs or Laptops of the network and look if this worked. 

Another problem now is, that the router doesn't know where to send packets adderessed to the subnets behind the other router. To solve that problem we need a router protokoll like RIP.

 

For IPv6: Router(config-if)#ipv6 rip riping ena 

Now we should be able to ping every host within the network.
