1.  Introduction

   BGP-LS ([RFC7752]) defines NLRI and attributes in order to carry
   link-state information.  New BGP-LS Link-Attribute TLVs are required
   in order to carry the Traffic Engineering Metric Extensions defined
   in [I-D.ietf-lsr-isis-rfc7810bis] and [RFC7471].

2.  Link Attribute TLVs for TE Metric Extensions

   The following new Link Attribute TLVs are defined:
