Enterprise VPN Activation
End-to-end flow for provisioning a multi-site MPLS L3VPN for an enterprise customer, from enquiry and solution design through design & assign, NSO activation, CPE deployment, phased site rollout, SLA baselining, and ongoing managed service monitoring.
Architecture Overview
An MPLS L3VPN connects multiple enterprise sites over the operator's MPLS backbone. Each site has a CE router connecting to the operator's PE router. VRFs on the PE isolate customer traffic. NSO or equivalent automates PE/CE configuration across the network.
Enterprise VPN Sites
HQ and branch offices with LAN. Each site connects via CE router. VAS products (managed LAN, managed firewall, FWA backup) may require public IP allocation for internet breakout or management.
CE Router (CPE)
Customer Edge router at each site. Operator-supplied, runs BGP/OSPF peering with the PE. Configured remotely via NSO.
MPLS Backbone
Operator MPLS core with P routers and label-switched paths. VRFs on PE routers provide per-customer traffic isolation.
PE Routers & NSO
PE routers host per-customer VRFs. NSO automates VRF, interface, and routing config across all PE/CE devices.
BSS/OSS Enablers
SOM orchestrates fulfilment, ROM configures resources. Network Inventory (EAI) provides topology. IPAM allocates IPs. ITSM/CMDB tracks CIs and SLAs.
