Labs/Lab02.md

+**UNDER CONSTRUCTION!**
+
+In this lab, we will set up a simple topology with [containerlab](https://containerlab.dev/) and configure two cEOS switches that we manage with the goSDN controller.
+
+**Please note: You need to have the lab-vm or all the software in [Prerequisites](Labs/Prerequisites) installed to run this lab.**
+
+The figure below shows what we want to set up using the goSDN-Controller, goSDN-CLI and gnmi:

+
+## Run the containerlab
+Go to the directory of gosdn and use following command:
+```
+make containerlab-start
+```
+
+## Download the folder below and place it into the artifacts folder of your gosdn folder
+[lab01.zip](uploads/e7bbf3f0575a4e471c8ba8862c0b2dde/lab01.zip)
+Or get it with wget:
+```
+wget https://code.fbi.h-da.de/danet/gosdn/-/wikis/uploads/e7bbf3f0575a4e471c8ba8862c0b2dde/lab01.zip
+```
+
+## Open a new terminal and start the CLI to talk to the controller (Do not close the  previous terminal)
+Build command prompt
+```
+make build
+cd artifacts
+./gosdnc prompt
+```
+![CLI_image](uploads/155116353627ae3070a53b3fdaeda421/CLI_image.PNG)
+
+## Login into the controller with the credentials 
+```
+login –controller 172.100.0.5:55055 --u admin --p (password)
+```
+
+### To get the (password) go to the previous terminal and use the following commands
+```
+docker logs clab-gosdn_csbi_arista_base-gosdn
+```
+
+In the end of the script a 16 character alphanumeric password is generated like this: “Generated admin password: uyslboh15gjp9dne” (not the actual password, just an example)

+## Set up the PND ID
+```
+pnd use (Choose ID from the displayed menu)

+
+If you've cloned the goSDN repo from [here](https://code.fbi.h-da.de/danet/gosdn) and have all the requirements, then you can start the containerlab topology (which is defined below) using the command `make containerlab-start` from within the root of the repository
+
+
+## CLI and the controller
+
+### Setup centos devices
+Since we do not have access via gNMI on those devices, we have to perform some steps manually, within the container itself.
+
+First we have to get into the centos device via 
+`docker exec -it clab-gosdn_csbi_arista_base-centos1 bash`
+and run the following commands:
+```
+[root@centos1 /]# ip address add 10.0.0.100/24 dev eth1
+[root@centos1 /]# ip route del default
+[root@centos1 /]# ip route add default via 10.0.0.1 dev eth1
+[root@centos1 /]# exit
+```
+
+`docker exec -it clab-gosdn_csbi_arista_base-centos2 bash`
+
+```
+[root@centos2 /]# ip address add 192.168.0.100/24 dev eth1                                                           
+[root@centos2 /]# ip route del default                                                                               
+[root@centos2 /]# ip route add default via 192.168.0.1 dev eth1                                                      
+[root@centos2 /]# exit
+```
+
+## Testing our setup 
+### Ping the centos devices with the ip's 
+```
+docker exec -ti clab-gosdn_csbi_arista_base-centos1 ping 192.168.0.1
+docker exec -ti clab-gosdn_csbi_arista_base-centos2 ping 10.0.0.1
+```
