networking Lab

Wasup! I'm doing a lab on cisco packet tracer and I'm assigning Ip addresses. one step says Assign the last usable  address of subnet 6 to the office 1 network CEO end devices. Also, assign a subnet mask and the default gateway ( first  address in the subnet) can I get some help on this please

Hi

 Sure you can get help here. But you need to provide more information.

Attach your project here, just zip it before attach.

The last usable IP address depends on the mask. For example

192.168.1.0 with mask 255.255.255.0 the last usable IP would be 192.168.1.254.

Thank youu!! so much I'm dedicated to learning networking.

I'm stuck under Assigning Ip address step 6, I assigned an Ip address to my device office 1, but I'm not understanding the Note. where it states Also assign a subnet mask and the default gateway (first address in the subnet ) ?? what does the lab mean by that

[Flavio Miranda]

You are expected to take the 172.16.0.0/24 and divided into 8 subnetworks, right?

Here it is, 8 subnetwork.

Network Address	Usable Host Range	Broadcast Address:
172.16.10.0	172.16.10.1 - 172.16.10.30	172.16.10.31
172.16.10.32	172.16.10.33 - 172.16.10.62	172.16.10.63
172.16.10.64	172.16.10.65 - 172.16.10.94	172.16.10.95
172.16.10.96	172.16.10.97 - 172.16.10.126	172.16.10.127
172.16.10.128	172.16.10.129 - 172.16.10.158	172.16.10.159
172.16.10.160	172.16.10.161 - 172.16.10.190	172.16.10.191
172.16.10.192	172.16.10.193 - 172.16.10.222	172.16.10.223
172.16.10.224	172.16.10.225 - 172.16.10.254	172.16.10.255

6 Assign the last usable addresses of subnet 6 to the Office1 network CEO end devices. Also, assign a subnet mask and the default gateway (first address in the subnet).

Subnet 6 is: 172.16.10.160/27 (255.255.255.224)

Office 1 is connected to R1. You need to assign one IP address to the Router´s interface GigabitEthernet 0/0:10. You can use 172.16.10.161 255.255.255.224 (First address of the subnet)

Last usable address of this subnet, you assign to  PCs.

IP:172.16.10.162 

Mask: 255.255.255.224

Gatewa:172.16.10.161

IP:172.16.10.163

Mask: 255.255.255.224

Gatewa:172.16.10.161

172.16.10.164

Mask: 255.255.255.224

Gatewa:172.16.10.161

172.16.10.165

Mask: 255.255.255.224

Gatewa:172.16.10.161

172.16.10.166

Mask: 255.255.255.224

Gatewa:172.16.10.161

172.16.10.167

Mask: 255.255.255.224

Gatewa:172.16.10.161

ahh okay! once in the router CLI, en, config t, interface gig 0/0.10, Ip Address 172.16.10.161. 255.255.255.224, now do i open access that interface to trunk and then encapsulation the with dot1q, then exit or just exit after input of Ip address then assign the rest of the subnet range to the other pcs in office 1

[Flavio Miranda]

config t

interface gig 0/0.10

encapsulation dot1q 10

Ip Address 172.16.10.161 255.255.255.224

end

This is it to router

[shanej2118]

cool, how do I assign ip addresses to the pcs on that network now. 

[shanej2118]

I do it through the routers CLI ? now assigning to CEO 1 , Copyrightre 1 & Dialer 1 what are th cmd for assign those pics ?

[Flavio Miranda]

No. Double Click on the PC and open the configuration window.

 There you add IP, mask and gateway  

[shanej2118]

okay got it 

[shanej2118]

where does the default gateway input ?

[Flavio Miranda]

Use the Desktop tab.
