This document discusses deploying MPLS L3VPN. It begins with an overview of MPLS and VPN terminology. It then covers the MPLS reference architecture and different node types. It describes how IP/VPN technologies use separate routing tables at provider edge (PE) routers to provide independent virtual routing and forwarding (VRF) instances for each VPN customer. The control plane uses multiprotocol BGP (MP-BGP) to distribute VPN routes between PE routers using route distinguisher (RD), route target (RT), and labels. The forwarding plane uses these labels to encapsulate and transport customer IP packets across the MPLS core. The document then discusses various IP/VPN services including load sharing, hub-and-spoke
