Goal

The goal of this assignment was to import, attach and configure the Vyos router to the network that was made during the second assignment, reconfigure switches and Lubuntus by adding VLANs.

Physical topology

Logical topology

Network settings of the Switch 2

Adding "brave_new_vlan"

Switch 1

Switch 2

Configuration of two VLAN interfaces on the Vyos router

show interfaces on Vyos

show ip route on Vyos

Manual change of the network settings on Lubuntus

Lubuntu 1

Lubuntu 2

ip addr on Lubuntu 1

lubuntu@lubuntu-virtualbox:~$ ip addr

traceroute Lubuntu 1 --> Lubuntu 2

Great! Our router connection is working and now we can see .62 and .126 besides Lubuntus IPs.

Now let's add "network_device" vlan and check if it works

show interfaces command on vyos after adding the "network_device" vlan

show ip route command after adding the "network_device" vlan

Configuration of switches after adding all the necessary ports, VLANs and configuring an ip adress for "network_devices"

Switch 1

Switch 2

Configuration of the Vyos

vyos@vyos# show

         duplex auto
         hw-id 08:00:27:2d:bd:e9

         vif 40 {

         }
         vif 228 {

     ssh {
         port 22
     }

     }
     console {

         }
     }
     host-name vyos
     login {
         user vyos {
             authentication {
                 encrypted-password $6$EKHTHLPZKERb/Hdz$Mlc3fond5GwtNcrL5u/SW6IceGrFY7xak7XxJcwWSYh1tVVrjs1rKlrL8N1edYx4KyvhFpRLuRmyku1xfzEVi0
                 plaintext-password ""
             }
             level admin
         }
     }
     syslog {
         global {
             facility all {
                 level info
             }
             facility protocols {
                 level debug
             }
         }
     }
     time-zone UTC
 }

Let's now try ssh to Vyos

ssh Lubuntu 1 --> Vyos

ssh Lubuntu 2 --> Vyos

Connectivity tests
