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 Entropy Label Capability (ELC), on that tunnel. 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
IS-IS. These mechanisms are particularly useful, where label
advertisements are done via protocols like IS-IS.
