Hi,
full mesh is recommended in several network design guides also when not using VSS/VPC.
E.g. Cisco Borderless Campus 1.0 Design Guide and Enterprise Campus 3.0 Architecture Guide:
"As a general best practice to build resilient network designs, it is highly recommended to interconnect all network systems with full-mesh diverse physical paths. This network design automatically creates multiple parallel paths to provide load-sharing capabilities and path redundancy during network fault events. Deploying a single physical connection from any standalone campus system to separate redundant upstream systems creates a “triangle”-shaped physical network design that is an optimal and redundant design, in contrast to the non-recommended partial-mesh “square” physical network design."
Does anyone know why exactly square is not recommended and what are the essential benefits of full mesh next to load-sharing?
We did not found any further information in cco concerning this.
Best Regards
