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, referred to as Readable Label-stack Depth (RLD),
   in the cases where stacked LSPs are used for whatever reasons.  This
   document defines mechanisms to signal these two capabilities using
   OSPF.  These mechanisms are useful when the label advertisement is
   also done via OSPF.  In addition, this document introduces the Router
   Non-OSPF Functional Capabilities TLV for advertising OSPF router's
   actual non-OSPF functional capabilities.  ELC is one of such non-OSPF
   functional capabilities.
