Distribute the Entropy Label Capability (ELC) in an IS-IS network

You can distribute ELCs across all the routers in an IS-IS network. ELC indicates the capability of a router to interpret Entropy Label Indicator (ELI), remove ELI/EL, and inspect next label. Entropy Readable Label Depth (ERLD) is the number of labels the router is able to read in a label stack and use it for its load balancing function. This can be used in cases of stacked labels (SR-MPLS) to insert ELs at ingress routers based on the different ELC and ERLD of the routers along its path.
