Learn how to deploy network virtualization using tunneling services such as MPLS, VRF-lite, to EoMPLS. Tunneling deals with creating separate routing domains on the same hardware infrastructure. There is Layer 3 VPNs (L3VPN) using either MPLS VPN which is intended for larger networks and Multi-VRF CE (or VRF-lite) for medium to smaller sized networks. And there is Layer 2 VPN (L2VPN) technologies which extends Layer 2 services (VLANs) across a Layer 3 network that may be utilizing MPLS VPN.
