Context: I have 3 servers,
2x dell poweredge each with 4x 1gbs cards
1x workstation with 2x 10gbs cards
I also have a 48 port switch (1gbs)
I need to get vms to be able to talk to vms on a different server. (yes they are clustered)(yes i downloaded all the SDN things)(yes MTU is 1450).
This is the start of creating a, "cyber range". Im going to have emulated users doing malicious activity so I can host blue teaming excersices and eventually red teaming as well. I intend to have people plug into the switch and rdp into a box to do this training.
Ive tried simple sdn but the vms wont talk to eachother (ping). I read that for simple sdn, it only allows vms on one node to communicate.
I need help with the process of choosing which SDN option (simple, VLAN, VXLAN, etc...) I also need help with the configuration of this. I cant seem to get it to work.

This is what the network information looks like for PC1 and PC2.
PC2 = (192.168.1.75), PC3 = (192.168.1.76)
I have recently used link aggrogation to use all of my network slots to help with speeds and also ceph. For this instance, I freshly wiped all of the servers and am only using one ethernet port on each machine until i solve this isssue.
When I create a VXLAN, i set the dhcp to be 10.10.1.1/24 but it keeps assigning me to 169.254.0.0/16
Also checking IPAM, nothing is updated.
When doing the simple SDN, i didnt have this problem, the DHCP worked and the IPAM updated. I just couldnt ping the other machines.
