What exactly means that WLC acts as proxy ETR? I am aware that proxy ETR is used in order for LISP sites to be able to communicate to non-LISP sites but how does it relate to fabric WLC?
i'd also be interesting to hear on this. where did u read this statement? only applicable case could be eWLC on BN imho, but again it wouldnt be anything to do with VXLAN-handoff for WLC imho
I would say that the statement is wrong, as the WLC is just an ETR, as it registers EIDs to the CP, but not a proxy ETR ; WLCs do not support VXLAN or LISP encapsulation, its purely control plane.
bc as part of Fabric underlay with LISP control plane to make its job as ETR i must have its RLOC route in Underlay as /32. it's a requirement for all RLOCs in SDA Fabric.
as @jalejand it's misconception , i'd say it came from Fabric WLC in mixed mode , where bot WLC & Fabric APs can be deployed with legacy centralized SSIDs. In this case WLC is operating as L2 handoff device for clients in that SSIDs. But it has nothing to do with LISP. BRKCRS-2502.pptx (ciscolive.com) slide 129
