Abstract 

   The International Telecommunication Union Telecommunication 
   Standardization Sector (ITU-T) has extended the Recommendation G.709 
   to support beyond 100G (B100G) features. Corresponding Open Shortest 
   Path First - Traffic Engineering (OSPF-TE) routing protocol 
   extensions are included in this document.

   1. Introduction 

   G.709 [G.709-2016] defines the interfaces to Optical Transport 
   Network (OTN) and includes new features to support beyond 100G 
   (B100G). In order to advertise this information in routing, this 
   document extends the encoding specific to OTN technology for use in 
   GMPLS OSPF-TE as defined in [RFC7138].  

   Routing information for Optical Channel (OCh) layer is beyond the 
   scope of this document. Please refer to [RFC6163] and [RFC6566] for 
   further information.  

   2. Terminology  

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this 
   document are to be interpreted as described in [RFC2119].

   3. OSPF-TE Extensions for B100G  

   As discussed in [GMPLSv5-fwk], OSPF-TE must be extended to be able 
   to advertise the 5G Tributary Slot Granularity, the multiplexing 
   capabilities of ODUCn connection requests, and the support 
   information of OTUCn sub rates (OTUCn-M).
