Change:
related L2VPN types.  More details are provided in es. The 'vpn-services' container maintains the set of L2VPN services <del> managed in the service providers network.  The module allows to </del> <ins> managed in the service provider's network.  The module allows to </ins> create a new L2VPN service by adding a new instance of 'vpn-service'. The 'vpn-service' is the data structure that abstracts the VPN service (l2_vpn_service).

Discussion:
Abstract s/This document defines a L2VPN/This document defines an L2VPN/ Section 2 s/contains information of the service providers/contains information of the service provider’s/ s/management of the service providers network/management of the service provider’s network/ s/Is a service providers that offers/Is a service provider that offers/ …between Customer Edges (CEs) and PEs… You expand CE but never PE (until the acronym section). I thought it might be good for maximum clarity to outright define CE and PE in your terminology section. Section 6.1 s/managed in the service providers network/managed in the service provider’s network/ Section 6.5 s/Global parameters profile are defined/Global parameters profiles are defined/ You misspelled ce-vlan-cos-preservation here and in the YANG module below. Since this is a leaf, it really should have correct spelling. Section 6.6.1 s/The asigned RT can be/The assigned RT can be/ Section 6.6.2 s/Address Resolution Protocol (ARP) and Nighbour Discovery (ND)/ Address Resolution Protocol (ARP) and Neighbor Discovery (ND)/ On this, should you have a reference for ARP and ND? Section 6.7.1 You mention LAG and LACP here and below in the module. But I never see a reference or expansion for either. I think both the text and the module would benefit from both. Section 6.7.4 s/they take precendence over the one inlcudes/they take precedence over the one includes/ In your two IANA modules you have identities for PPP and VPLS and a couple of others where the description is the identity name itself. This is where I wonder if slightly better descriptions would add more clarity. At least expanding the acronym would be useful IMHO. YANG module s/The RObust Header Compression (ROHC) Framework/The Robust Header Compression (ROHC) Framework/ YANG module Concerning identity “precedence-type”: First, you misspelled “backup”. You say active and backup here, but you use primary and backup below. I typically see primary with secondary and active with backup. Either way, I think you need to be consistent.

Also, since the base identity mentions the two defined sub-identities, should this really be an enumeration? Or should you just simplify this description so as not to mention any possible sub-identities? YANG module s/Indicates whether BGP auto-discovey/Indicates whether BGP auto-discovery/ s/Sets the indentifier of the VPN node/Sets the identifier of the VPN node/ s/contex of a VPN/context of a VPN/ s/Controles/Controls/g s/symetric/symmetric/ s/automatically assigned either withor/automatically assigned either with or/ s/maixmum/maximum/g YANG module Concerning leaf group-color: Okay, dumb question. What does a string for color provide here? While I’ve seen the concept of color used a lot in VPN examples, a free-form string that should be a color seems over-done here. The group-id is another open string. Why couldn’t that also be a color? I’d love to see some canonical reference that explains color use (if there is one). YANG module Concerning the number of different MTU-related leafs: The PW interface MTU is limited to 16-bits. Does it make sense to have a 32-bit service MTU here, then? Other than the pw-mtu, the other MTU leafs are all 32-bit, and I wonder if they shouldn’t all be 16. YANG module Concerning leaf color-type: Here is another use of color, but this time at least tied to an identity. Why couldn’t the other use also use this identity?
