City documentation labels the DCI border device a “stitch PE.” In JNCIP-DC DCI terms, what role does that name map to?
Select an answer to reveal the explanation.
Short Explanation
“Stitch PE” is ops slang for the border that sews two overlay fabrics together. It is the DCI gateway role—not a plain access leaf or a pure underlay spine. When docs say stitch PE, think interconnect border.
Full Explanation
In DCI discussions, a stitch PE/border performs stitching between site overlay domains—joining or translating EVPN-VXLAN contexts across the interconnect. That is distinct from an ordinary server-facing leaf, an underlay-only spine reflector, or a ZTP/management host.
