Layer 3 MPLS VPN Service Design

The design of the Globenet Layer 3 MPLS VPN service caters to both “managed” and “unmanaged” access. The managed service allows Globenet to supply and manage the customer access equipment. The unmanaged service just provides connectivity to the Layer 3 MPLS VPN service; no management of the customer access equipment is deployed. The vast majority of Globenet customers use the managed service, with only a few large Enterprises taking the unmanaged service.

Many aspects of the MPLS VPN design (such as PE router engineering guidelines, load-balancing support, naming conventions, and so on) are as detailed in previous chapters. Therefore, we will not cover them again here. Unless otherwise stated, Globenet uses all the Layer 3 MPLS VPN design best practices we have already detailed. Because Globenet is an international service provider, providing a worldwide service portfolio, this chapter concentrates on the aspects of the design that are specific to these types of providers.
