In this lab, you need to configure a grid tunnel.
So in this lab, we need to configure a jewelry tunnel between customer one and Customer two.
We've been told that we need to configure the customer routers to use a DHCP addresses on the internet
interfaces and static IP addresses on the internal interfaces.
So let's start with customer rather one.
I'll go to configuration mode and then go on to gigabit 001.
The interface is currently shut, so I'm going to shut the interface and then I'll configure an IP address
using DHCP.
As you can see, an IP address has been allocated via DHCP.
An IP address of 8.8 to 10.2 has been allocated.
I'll go onto interface gigabyte 000.
No shut of the interface and configure an IP address of ten 111 slash 24.
So show IP interface brief.
We can see that both interfaces are up.
This is the IP address on the Internet facing interface.
This is the IP address on the inside interface.
Internet address was assigned via DHCP internal or customer facing interface.
IP address was configured manually.
That happens because.
The ISP routers are configured as DHCP servers, so show IP DHCP binding.
We can see that this IP address was allocated to this MAC address.
Now we see a DHCP conflict here and that's because IP address 88 10.1 is part of the DHCP pool.
All IP addresses in the subnet are, but the router has this IP address configured on this interface.
So the ISP doesn't allocate its own IP address to the client, but allocates the next IP address in
the pool.
So again, show IP interface brief on the customer router.
This IP address was allocated via DHCP and the router can ping.
The ISP router.
I can do something similar on customer to.
So customer wrote a two show IP interface brief.
Both interfaces are administratively shut down.
So interface gigabit is 001 no shut IP address DHCP interface gigabit is 000.
And while I was typing that an IP address was allocated via DHCP to the router ip address on gigabit
000 is 10.1 to 2.1 slash 24 mask.
I'll no shutter that interface.
So show IP interface brief both IP addresses.
Or configured one dynamically and one statically show IP route shows us the routing table.
Notice a gateway of last resort has been configured and the router also has a default route to its ISP.
So ping eight eight 11.1.
The router can ping its default gateway or ISP router.
Can it ping?
Customer rather one so ping.
8.8.1.2.
Yes, it can.
We could do a trace as an example to that address and you can see that the traffic is going via the
Internet.
In other words, traffic is traversing these links to get to.
Customer rather one as an example.
The second hop is the IP address.
Third hop is the IP address.
So we have IP connectivity between customer one and Customer two.
The next step is to configure a DHCP pool on the customer routers to allocate IP addresses to the PCs
in the network.
So on customer roster one.
Conti ip dhcp pool and you could call this anything.
I'm just going to call it PC in the exam.
Follow the instructions.
But here, there's a little bit of leeway.
You can decide what you want the pool name to be.
Network is going to be this.
Subnet mask is going to be that.
Default router will be ten 111.
So show ip dhcp binding.
We don't have any bindings yet.
Let's look at the PC.
So on its configuration, we need to configure it to use a DHCP.
Go to Desktop Command prompt.
IP config notice it has a got an IP address ten 112 ping ten 111 PC can ping.
Customer Writer one And on the customer roster we can see again that.
There was an address conflict.
So the Rada allocated ten 112 rather than ten 111 to the client.
You could create an exclusion range for your pool.
If you want to make sure that a separate range of addresses are used for the client PCs.
We need to do something similar on customer rather too.
So t ip dhcp pool pc network will be ten 1 to 0.
With the mosque slash 24 mosque.
A default router will be ten 1 to 1.
So show ip dhcp binding.
No bindings yet.
Configure the PC.
To use DHCP go to desktop command prompt.
IP config IP address has been allocated to the PC.
So on the router show IP DHCP binding, the IP address has been allocated to the PC.
So we've successfully created DHCP pools on the customer routers to allocate IP addresses to the PCs.
We now need to configure a red tunnel between customer router one and two so that the PC can ping each
other.
