OSPF Multi-Area Network Diagram with BGP, EIGRP, and Virtual Link #1479747 (License: Personal Use)

The image depicts a hierarchical Cisco-style routed network with eight routers (R1-R8) organized into four OSPF areas: Area 0 (backbone), Area 1 (NSSA), Area 2 (discontiguous, connected via virtual link between R1 and R4), and Area 3 (stub). R4 runs BGP to peer externally, while R8 connects to an EIGRP domain. Dashed ovals denote area boundaries and protocol domains.

Used in networking documentation, certification study guides (e.g., CCNP ROUTE), or vendor training materials to explain OSPF area design, virtual links, and redistribution between routing protocols. Matches user intent for visualizing multi-protocol enterprise topologies.
