In a VXLAN EVPN fabric, L4-L7 connectivity play a vital role in securing and optimizing network traffic. L4-L7 services are typically connected to the leaf switches, often referred to as service leaf switches.
The choice between a dual-attached and single-attached L4-L7 service node design for a VXLAN EVPN fabric depends heavily on the specific requirements of your network services and the overall deployment strategy. Here’s a breakdown of both approaches along with key considerations:
Both dual-attached (vPC) and single-attached (PC) designs are supported and have their merits and drawbacks. Through thorough assessment of service requirements, availability demands, management complexity, and network performance expectations, selecting the most fitting approach for your VXLAN EVPN fabric deployment is achievable. Keep in mind, the ideal design is contingent on your unique business context and technical constraints.
