Okay.
So in this lab, we've been told to configure the network so that calls can be made between the IP phones
and we need to ensure that we have connectivity between devices in this network.
I'm going to start with the configuration of the Cisco router.
But the writer has just booted up show IP.
Interface brief shows us that no IP addresses are configured on the router.
So first thing I'll do is go on to F zeros, slash zero.
I could not shatter this interface, but I'll leave that till later.
So I'll go on to the sub interface.
If a zero slash is 0.1, I'll configure an IP address of ten .1.1.25 for.
Per these instructions on a VLAN one.
Going to use a slash 24 mosque.
And notice the problem.
I need to type encapsulation dot one q.
Specify a vlan in this case vlan one and then I need to make it the native VLAN.
In other words, the untagged vlan.
And now I can put an IP address on the interface.
So do show run shows us.
The configuration of the sub interface.
I'm going to give the router a name just because I like doing that so that I know which device I'm working
on.
I'll create the next sub interface, which is sub interface 100.
That's for VLAN 100.
The sub interface numbers don't have to match the subnet.
I just like to do that to make it easier to troubleshoot.
VLAN is going to be 100.
It's not the native VLAN.
IP address is ten one 102.4 subnet mask.
So do Shia run?
We've got two sub interfaces configured.
I'm going to configure Sub Interface 101.
IP address is ten 1101254 slash 24 mask.
And again, I need to configure the encapsulation as a VLAN 101.
And then I can configure the IP address.
So verification.
We've got three sub interfaces configured on the router.
That looks good.
I now need to configure dhcp pools under the router.
So ip dhcp pool.
Give it a name.
I'm just going to call this PC's.
You could have called that data if you preferred.
Name doesn't really matter.
Subnet mask is going to be a slash 24 mask.
Default router is going to be ten 125 for a DNS server is going to be the router.
So verification days are configuration of the DHCP pool for the pcs.
I need to do something similar for the phones.
You could have called this voice or phones.
It doesn't matter.
Again, use whichever term you want in the exam.
Follow what they tell you to do.
Network is that default gateway is going to be the router option 150 is the TFTP server, so we need
to specify that with an IP address being of the router, the phones will get their configuration from
the router.
Now again, you may want to create an exclusion range so you could do something like IP, DHCP excluded
address and specify the range of addresses that are going to be excluded for, let's say, the data
VLAN.
And the voice vlan.
I've just chosen some arbitrary values here.
In the exam, follow what they tell you to do.
It's really up to you in the real world.
Decide how many addresses you need to allocate and how many need to be excluded for servers.
That's quite a big range for a small network like this.
So I've configured the router with inter VLAN routing as well as DHCP pools.
I'm now going to configure the switch and then I'll configure the telephony service.
