An architect must develop a campus network solution that includes: - logically segmented and isolated networks - ability to communicate between network segments when required - support for…

VSS (Virtual Switching System) provides high availability and simplified management but does not inherently support overlapping IP addresses or provide the same level of logical isolation as VRF-Lite.

802.1Q (VLANs) provides Layer 2 logical segmentation, and HSRP offers first-hop redundancy, but neither technology supports overlapping IP addresses across different logical segments.

vPC (Virtual Port Channel) enhances high availability for Nexus platforms, and HSRP provides first-hop redundancy. These technologies do not provide the capability for overlapping IP addresses across different logical network segments.

VRF-Lite (Virtual Routing and Forwarding Lite) allows a single router to maintain multiple independent routing and forwarding tables, providing excellent logical segmentation and isolation. Crucially, each VRF can have its own IP address space, enabling support for overlapping IP addresses. OSPF, a widely available IGP, can be configured within each VRF to provide necessary routing, meeting all specified requirements.
