EIGRP/OSPF Routing Architecture with VLAN Segmentation Diagram #55636 (License: Personal Use)

The image depicts a multi-layered enterprise network architecture where four EIGRP/OSPF-enabled routers are interconnected-two at Layer 3 and two at Layer 2-with cross-connections ensuring redundancy. Each router handles specific VLANs: VLAN 120 and 20 for data and voice on the left, and VLAN 140 and 40 on the right, each with associated IP subnets (10.1.120.0, 10.1.20.0, etc.). The red and blue arrows indicate Layer 3 and Layer 2 traffic flows respectively.

Used in networking documentation, Cisco certification study guides, or IT infrastructure presentations to explain hierarchical routing, VLAN segmentation, and protocol interoperability between Layer 2 switching and Layer 3 routing domains.
