Abstract:
   Multiprotocol Label Switching (MPLS) has defined a mechanism to load
   balance traffic flows using Entropy Labels (EL).  An ingress Label
   Switching Router (LSR) cannot insert ELs for packets going into a
   given tunnel unless an egress LSR has indicated via signaling that it
   has the capability of processing ELs, referred to as Entropy Label
   Capability (ELC), on that tunnel.  In addition, it would be useful
   for ingress LSRs to know each LSR's capability of reading the maximum
   label stack depth and performing EL-based load-balancing, referred to
   as Entropy Readable Label Depth (ERLD), in the cases where stacked
   LSPs are used.  This document defines a mechanisms to signal these
   two capabilities using OSPF and OSPFv3.  These mechanisms are
   particularly useful in the environment where Segment Routing (SR) is
   used, where label advertisements are done via protocols like OSPF and
   OSPFv3.
