-BGP Link-State
-==============
-
-Overview
---------
-
-BGP Link-State (BGP-LS) is an extension of the BGP protocol designed to
-redistribute information from an IGP database to a remote controller (most
-likely a Path Computation Element - PCE). BGP-LS does nothing more than
-transport IGP information. Therefore, it cannot be used to replace a Link State
-routing protocol like OSPF and IS-IS.
-
-Historically, the only way to get a network controller to collect an IGP
-database was to have it participate in the IGP itself as if it were a standard
-router. Since the controllers were usually located far from the IGP area,
-tunnels such as GRE were used to connect the controllers to the IGP area. This
-method was so impractical that an alternative solution was imagined: using the
-already deployed inter-domain BGP protocol to redistribute the various IGP
-databases.
-
-BGP Link-State as defined in `RFC7752
-<https://www.rfc-editor.org/rfc/rfc7752.html>`_ uses the AFI 16388 and SAFI 71.
-The BGP Link-State pseudo-prefixes distributed by the `NLRI (Network Layer
-Reachability Information)` uniquely define the following
-IGP information:
-
-- Nodes
-- Link
-- IPv4 Prefix
-- IPv6 Prefix
-
-They are called descriptors. In addition, a new type of BGP Attributes called
-"BGP-LS attributes" carries the other information related to a descriptor.
-
-NLRI and attribute information for BGP-LS is organized using the TLV format
-already used by IS-IS LSPs and OSPF opaque LSAs. The `list of TLV code points
-<https://www.iana.org/assignments/bgp-ls-parameters/bgp-ls-parameters.xhtml#node-descriptor-link-descriptor-prefix-descriptor-attribute-tlv>`_
-is maintained by IANA.
-
-Current implementation
-----------------------
-
-The current version can participate in BGP Link-State AFI / SAFI with
-third-party routers and forward the BGP Link-State descriptors and attributes to
-other routers. However, it can not generate BGP Link-State data from OSPF and
-IS-IS.
-
-IANA maintains a `registry of BGP-LS NRLI descriptor types
-<https://www.iana.org/assignments/bgp-ls-parameters/bgp-ls-parameters.xhtml#nlri-types>`_.
-Only the following RFC7752 NRLI types are supported by the current version:
-
-- Nodes
-- Link
-- IPv4 Prefix
-- IPv6 Prefix
-
-The BGP-LS attribute TLVs for these NLRI types are transmitted as is to other
-routers which means that all the current and future version are already
-supported.
