Site connectivity: L2/L3 VPN

What it is

An L2 VPN extends Ethernet connectivity between sites, while an L3 VPN provides routed IP connectivity through the service provider network.

Why it matters

The choice affects routing control, broadcast domains, scalability and how much responsibility remains with the customer versus the carrier.

What shapes the design

• Need for a shared L2 segment
• Site address plan
• Bandwidth and latency
• Handover and resilience points

QMTS delivery scope

We select the appropriate service model, define addressing and routing, coordinate carrier handoffs, configure edge devices and test site-to-site communication and failover.

Customer deliverables

A working private inter-site network with documented topology, routing boundaries, handoff parameters and acceptance results.

Typical use cases

Branch interconnection, data-center connectivity, campus extension, migration projects and private access between critical business locations.

Delivery lifecycle

• 01 Requirements discovery and current-state assessment.
• 02 Architecture, dependencies and implementation planning.
• 03 Technical specification, configuration baseline and delivery preparation.
• 04 Implementation, integration, testing and controlled commissioning.
• 05 As-built documentation, operational handover and managed support where required.

Before we start

To scope a project, describe the goal, users and sites, current systems, timing constraints and desired outcome. Solution scope and service terms are defined after assessment.
