	3.2. L2 VPN Service		3.2. VPN Profiles
			The 'vpn-profiles' container (Figure 4) allows the network provider
			to define and maintain a set of common VPN profiles
			[I-D.ietf-opsawg-vpn-common] that apply to one or several VPN
			services. The exact definition of the profiles is local to each
			network provider.
			This document does not make any assumption about the exact definition
			of these profiles. How such profiles are defined is deployment
			specific. The model only includes an identifier to these profiles to
			ease identifying local policies when building a VPN service. As
			shown in Figure 4, the following identifiers can be included:
			o 'cloud-identifier': This identifier refers to a cloud service.
			o 'encryption-profile-identifier': An encryption profile refers to a
			set of policies related to the encryption scheme(s) and setup that
			can be applied when building and offering a VPN service.
			o 'qos-profile-identifier': A QoS profile refers to as set of
			policies such as classification, marking, and actions (e.g.,
			[RFC3644]).
			o 'bfd-profile-identifier': A Bidirectional Forwarding Detection
			(BFD) profile refers to a set of BFD [RFC5880] policies that can
			be invoked when building a VPN service.
			o 'forwarding-profile-identifier': A forwarding profile refers to
			the policies that apply to the forwarding of packets conveyed
			within a VPN. Such policies may consist at applying Access
			Control Lists (ACLs).
			o 'routing-profile-identifier': A routing profile refers to a set of
			routing policies that will be invoked (e.g., BGP policies).
