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.
