Hi Authors,

I see the following words in the introduction.
"   Recently, mechanisms have been defined to signal labels via link-
   state Interior Gateway Protocols (IGP) such as IS-IS [RFC8667].  "

It's not clear to me what the " mechanisms " are. Could you please add some reference or text on this?

Thanks,
Tianran

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 Label Switched Path (LSP) unless an egress LSR has indicated
   via signaling that it has the capability to process ELs, referred to
   as the Entropy Label Capability (ELC), on that LSP.  In addition, it
   would be useful for ingress LSRs to know each LSR's capability for
   reading the maximum label stack depth and performing EL-based load-
   balancing, referred to as Entropy Readable Label Depth (ERLD).  This
   document defines a mechanism to signal these two capabilities using
   OSPFv2 and OSPFv3 and BGP-LS.
