Virtual Port Channel (VPC) “Fabric”
54Presentation
• VPC Northbound & Southbound
• More efficient than native STP
• STP is still running
• Another good workaround
• Configuration can become complex as switch counts grow

L3-Based Fabrics
55Presentation
• Every link forwarding
• L3 ”routing” convergence
• Fast convergence (properly tuned)
• STP might still exist, not in the “fabric”• Drastic reduction in blocking & convergence
• VPC still needed at edge
• Spine/Leaf: • Flexible design
• Consistent hop count & latency Host or Switch
