:Please based on this [https://scs.senecac.on.ca/~raymond.chan/ops535/network/ops535_virtual_lab_network_diagram.pdf OPS535 Virtual-lab Network Diagram] to figure out the necessary network configuration so that all your VMs are reachable from all other VMs (i.e. all the VMs in our OPS535 Virtual-lab using the 192.168.x.y address space. Click [https://github.com/rayfreeping/ops535/raw/master/vitrual_lab/ops535_VLS_routing_slides.pdf here] for more details network diagram for routing configuration.

: <font color='red'>IMPORTANT:</font> All the IP address 172.20.x.y (where 172.20.x is your network number, and y is the host part of the IP address) are assignment to your VMs by the DHCP server in the OPS535 Virtual-lab. This range of IP addresses are normally assigned to the virtual network adaptor named ens192 (may be changed in the future) on each VM. Please do not change these IP addresses, otherwise, you will cut the VM off from the network and you won't be able to ssh back into it again from matrix.
