A public-health clinic must isolate SCADA from corporate users on the same PE-CE style routers without running MPLS in the campus. Which construct provides separate routing tables on those shared boxes?
Select an answer to reveal the explanation.
Short Explanation
VRF-lite is separate filing cabinets in the same clerk’s office—one for SCADA, one for corporate—without needing an MPLS warehouse out back. Shared routers, isolated RIBs. Address overlapping alone won’t stop routes from mixing in one table.
Full Explanation
VRF-lite instantiates multiple VRFs on a router so interfaces and routes stay in separate tables without mandating MPLS label switching in the campus. That fits multi-tenant or SCADA-versus-corporate separation on shared PE-CE style devices. A single global table—even with RFC1918—does not isolate routing, and PortFast or VTP cannot provide VRF separation. Use VRF-aware interfaces and routing, with carefully controlled leaking only where shared services require it.
