The router supports the MPLS entropy label (RFC 6790) on RSVP-TE LSPs used for IGP and BGP shortcuts. LSR nodes in a network can load-balance labeled packets in a more granular way than by hashing on the standard label stack. See MPLS Entropy Label and Hash Label for more information.
To configure insertion of the entropy label on IGP or BGP shortcuts, use the entropy-label command under the configure>router context.
