In this lab, you need to configure a grid tunnel geometry or generic routing.
Encapsulation is a tunneling technology that allows you to create a point to point tunnels over an IP
network such as the Internet.
Multiple protocols can be encapsulated over Jori and you can run routing protocols across a geo tunnel.
The disadvantage of geo tunnels is that they don't support encryption.
If you want the added benefit of jury encrypted tunnels, you typically encapsulate a grid tunnel over
an IP tunnel.
IP SEQ provides the encryption.
GRI allows you to encapsulate multiple protocols and run routing protocols across the grid tunnel.
Cisco Devices now support many types of tunnels such as DLM, VPN and others, but Jory is one of the
oldest and most simple tunneling technologies.
In this lab, you need to configure a GRC tunnel from customer one to Customer two via the Internet
routers in the topology.
There are three Internet routers, ISP router one, ISP router two and ISP router three.
Each of these routers is running BGP in a separate autonomous system.
The BGP configuration has already been completed and as you can see here, ISP router two has two BGP
relationships.
So show IP BGP summary.
Shows us that the router has two BGP relationships.
To one relationship to ISP one and another to ISP three.
Here are the list of tasks that you need to complete in this lab.
You need to configure customer orders, see one and see two.
In other words, this rata and this router to use DHCP IP addresses on gigabit 001 and static IP addresses
as shown in the diagram on gigabit 000.
The ISP routers, ISP one and ISP three have been configured with DHCP and these routers will allocate
IP addresses to the customer routers.
So you need to configure these interfaces with DHCP and these interfaces with static IP addresses.
You then need to configure a DHCP pool on the customer routers to allocate IP addresses to the PCs.
So on customer writer one and customer wrote a to create a DHCP pool and allocate IP addresses to the
PCS.
In these subnets, ensure that the PCs learn about their default gateways.
In other words, PC ones default gateway will be customer router one.
PC two's default gateway will be customer out of two.
You then need to configure a tunnel between C one and C two so that PC one and PC two can ping each
other using RFC 1918 addresses.
Network ten is an RFC 1918 address.
So these PCs will need to be able to ping each other via the Jio tunnel, use a tunnel interface of
tunnel zero on both Customer one and Customer two and use IP addresses of ten.
One, two, three, one and ten, one, two, three, two.
On the tunnel interfaces to enable routing between customer side one and customer side two, you need
to enable IGP and Autonomous System 100 and advertise this network via the Jio tunnel to customer router
one so that the router and the PC can ping both this IP address as well as PC two.
This network also needs to be advertised by IGP through the tunnel so that Customer two and PC two can
ping both the IP address and PC one.
So as a verification, make sure that the customer routers can ping each other on their gigabyte 000
interfaces and that PC one and PC to can ping each other.
These routers in the Internet such as I-spy two, will not learn about the Ten Network.
They should only know about the 8.8.6. X Networks.
Ten 000/8 is an RFC 1918 or private address.
So we are going to tunnel private addresses through the Internet via a tunnel so that these devices
can ping each other.
Even though the ISP routers don't know about those networks.
