Two municipal EVPN fabrics use different VNI number spaces, and border devices must join overlay domains for DCI. Which stitching concept applies?
Select an answer to reveal the explanation.
Short Explanation
Different VNI spaces are like different room-numbering schemes in two buildings. Stitching at the border is how you join those overlay domains without pretending they were always one fabric.
Full Explanation
VXLAN/EVPN stitching joins overlay domains at a border when fabrics do not share a single VNI namespace or overlay instance. Border devices translate or interconnect the overlays so tenants can communicate across independently numbered fabrics. Stitching is a DCI concept distinct from simply merging two sites into one underlay fabric.
