Question

Municipal ops says two VRFs are “stitched” because a static route leaks prefixes between them on a border router. For JNCIP-DC DCI concepts, how should that claim be corrected?

Accepted Answer

Overlay stitching joins L2/L3 EVPN-VXLAN domains at a DCI border, which is related to but not the same as ordinary VRF route leaking — Leaking routes between VRFs is like unlocking a door between two offices in the same building. Stitching overlays is more like linking two whole campuses that speak VXLAN/EVPN on each side. Related idea—traffic can meet—but not the same DCI concept.

Answer

Any IP route between VRFs is officially called EVPN stitching and needs no further distinction

Answer

Stitching always means only Type-5 EVPN routes; leaking IP prefixes is identical to L2 VNI stitch

Answer

VRF route leaking and overlay stitching are the same control plane because both move packets between tenants
