Test Objectives
The primary objective of this JVDE testing is the qualification testing of the 3-Stage Data Center Reference Design with Juniper Apstra and VMware NSX-T. The design is based on an ERB (Type 2 and Type 5) EVPN/VXLAN fabric with spine, server leaf, border leaf, and NSX-T Edge Gateway devices.
In the same way that server virtualization programmatically creates and manages virtual machines, NSX-T Data Center network virtualization programmatically creates and manages virtual networks. NSX-T Data Center works by implementing three separate but integrated planes: management, control, and data. These planes are implemented as a set of processes, modules, and agents residing on two types of nodes: NSX Manager and transport nodes.
The Juniper data center fabric is viewed as an external network, which is defined as a physical network or VLAN not managed by NSX-T Data Center. The NSX logical network or overlay network can be linked to an external network through a Tier-0 router or NSX Edge.
The goal is to ensure the design is well-documented and will produce a reliable, predictable deployment for the customer.
The qualification objectives include validation of blueprint deployment, device upgrade, incremental config pushes/provisioning, telemetry and analytics checking, failure mode analysis, and verification of host traffic.
Test Goals
This JVDE for integration of NSX-T with 3-Stage Fabric using Juniper Apstra focuses on the following:
- Design and deployment of NSX-T and vSphere components such as NSX-T Edge Node, ESXi servers, VDS switch, and port groups.
- Configuring NSX-Manager with Edge Nodes, Transport Nodes, Tier-0 and Tier-1 gateways.
- Connectivity with fabric border leaf switches using loopback and links.
- Apstra configuration for connectivity NSX-Edge Nodes, using Virtual Networks, Routing-Zone (VRF), connectivity templates for IP link, BGP, and static routes
- Validation of end-to-end traffic flow
- Test for any anomalies, view the VM, ARP, and MAC collection from Juniper Apstra.
In order to pass validation, the 3-stage Fabric with Juniper Apstra and NSX-T integration must also pass the following scenarios:
- East-West connectivity - Host connectivity between fabric connected hosts created by Apstra towards NSX managed hosts, covered in VMware NSX-T: Verify Overlay Connectivity (East-West).
- North -South connectivity – Connectivity between NSX Edge Node and border leaf switches proving external connectivity as covered in VMware NSX-T: Verify BGP Session on Edge.
