Charter looks good. Looking forward to discussion within the group.

> Charter: LSVR - Link State Vector Routing 
>  
> The Link-State Vector Routing (LSVR) Working Group is chartered to develop and document a hybrid routing protocol utilizing a combination of link-state and path-vector routing mechanisms.  The LSVR WG will utilize existing the IPv4/IPv6 transport, packet formats, and error handling from BGP-4 (RFC4271). Additionally, the BGP-LS NLRI encoding mechanisms defined in RFC7752 are utilized to facilitate Link-State Vector (LSV) routing information distribution. An LSV is intended to be specified as a data structure comprised of a link identification, link attributes, neighbor information, cost toward neighbors, and other attributes that are defined for control plane function and policy-based routing decisions.
>  
> The LSVR specification is initially focused on operation within a single datacenter (DC) with preliminary focus on specifying functionality within a single distribution domain.  Routing protocol functionality defined by LSVR would be typically routing within a datacenter's underlay routing plane. 
>  
> In order to achieve the noted objective, the working group will focus on standardization of protocol functionality, defining Link-State Vectors (LSVs), and defining standard path-vector route selection utilizing existing Dijkstra SPF based algorithm, BGP-4 protocol mechanics, and BGP-LS NRLI encoding.
>  
> For the purposes of the initial work within the LSVR WG, and until further specified by the WG, the following definitions apply to this charter.
>  
> - Link-State Vector - An LSV is intended to represent a data structure (data set) comprised of link identification, link attributes, neighbor information, cost towards neighbors, and other potential attributes that can be utilized to make routing decisions.
> - LSVR Distribution Domain - Initially scoped as a set of participating LSVR nodes in a single administrative domain.

> The LSVR WG is chartered to deliver the following documents:
>  
> - Publish Applicability Statement for the use of LSVR in the Datacenter - Target Status: Informational
> - Publish specification document describing LSV with standard Dijkstra SPF route/path selection (calculation) utilizing existing BGP protocol baseline functionality and BGP-LS packet encoding formats - Target: Standards Track (Based on draft draft-keyupate-idr-bgp-spf)
> - Publish specification documenting protocol extensions required to efficiently reuse BGP to distribute LSVs within an IPv4/IPv6 DC with scope to include privacy and security considerations - - Target: Standards Track
> - Publish YANG model specification for LSVR - - Target: Standards Track
>  
> LSVR Milestones:
>  
> - Applicability statement for LSVR in DCs: March 2019
> - LSVR with standard Dijkstra path selection: March 2019
> - LSV distribution using BGP transport: March 2019
> - YANG specification for LSRV: July 2019
