Duplicate MAC addresses being assigned

Post by priyanshuz » Sat Sep 12, 2020 6:44 am

I have 2 different labs in my EVE-NG. for instance, node 7 for both labs have the same mac address.

LAB1 : -> NODE ID 7 has 50:00:00:07:00:00 (vyos)
LAB2 : -> NODE ID 7 has 50:00:00:07:00:00 (fortigate)

What they have same MAC address ? How can we make sure that the MAC addresses doesn't overlap.

Please advise.

MAC address in the EVE is related by 2 factors:
User pod Nr and Node ID.
If same user admin (Pod 0) add node 7 in any of labs it will have same MAC.

Solution two ways:
Vital node which is connected to cloud, and this cloud can see ulti labs, avoid to use nodes with same ID...
Example: In LAB1 just add another vyos Node ID 8, and after delete that node ID7

Second solution:
Adding node to topology, you can set on first interface custom MAC address.
Right click on node and see MAC address field for edit.
