How it works

The provider tags customer traffic with MPLS labels and keeps routes in per-customer VRFs, so networks stay separated inside the provider core without any tunnel on your side.

Connects

Private enterprise networks

Protocols

MPLS, BGP, VRF

Typical users

Enterprises, Telecom customers

Main use case

Predictable, SLA-backed private WAN connectivity.

Advantages

Consistent latency and guaranteed bandwidth
Provider-managed

Limitations

Traffic is isolated but not encrypted — add IPsec if confidentiality matters
Expensive and slow to provision

Not safe on its own

This technology isolates traffic but does not encrypt it. Run IPsec or WireGuard on top if confidentiality matters.
