SPBm is a layer 2 technology that utilises IS-IS to form adjacencies between devices and share MAC address information. More detailed information can be found in link below
Images are available to download from GitHub. Please use 8.10 as earlier images are control plane only. Also, please note the interfaces to not map correctly on EVE-NG ie Gig1/2 in image is actually Gig1/1, Gig1/3 is Gig1/2 etc

Here we have a typical spine/leaf topology. Once all configured, vPC6 will be able to ping vPC8 and vPC7 will be able to ping vPC9. This will be achieved by using I-SIDs, which are basically service identifiers. These are assigned to VLANs and advertised by IS-IS to create a layer 2 segment between devices.

IS-IS adjacencies will now be up and the leafs advertising the respective I-SIDs. Configure IP addresses within the same subnet on the respective vPCs and you will have IP connectivity like below.
