If VLAN 3600 is for fabric discovery, wouldn’t that lean more towards a Fabric VLAN (D) since it’s about the fabric itself? Infrastructure sounds broader, but discovery might be more specific. Anyone remember exact docs on this?

B. It’s known that VLAN 3600 is used for internal fabric communication, so Infrastructure VLAN makes the most sense compared to Transit or Loopback options.

I’m pretty sure it’s B, Infrastructure VLAN. The VLAN 3600 is typically used for control and management traffic in ACI fabrics, which fits the infrastructure role. The other options don’t really align with what VLAN 3600 usually handles. D, Fabric VLAN, sounds close but is more general, while Infrastructure VLAN is the specific term I’ve seen tied to this VLAN number.

B imo, since Infrastructure VLAN is the usual default for fabric discovery VLANs like 3600. Transit and Loopback don’t quite fit the automatic setup context here.

B/C? I’m thinking it’s between Infrastructure VLAN and Loopback VLAN since those are common in fabric discovery, but not sure if VLAN 3600 is usually tied to Loopback.

Maybe D, Fabric VLAN? But is this specific to a certain ACI version or hardware model? Just want to be sure it’s always called that during discovery.
