Data CenterDesign Considerations

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

Host or Switch

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
