The router supports the MPLS entropy label (RFC 6790) for EVPN VPLS and Epipe services, and the Flow Aware Transport label (known as the hash label) (RFC 6391) on spoke-sdps bound to a VPLS EVPN service. This label allows LSR nodes in a network to load-balance labeled packets in a much more granular fashion than allowed by simply hashing on the standard label stack. The entropy label can be enabled on BGP-EVPN services (VPLS and Epipe).
To configure insertion of the entropy label on a BGP-EVPN VPLS or Epipe, use the entropy-label command in the bgp-evpn>mpls context. Use the entropy-label command under the spoke-sdp context to configure insertion of the entropy label on spoke-sdps bound to a BGP-EVPN VPLS. Note that the entropy label is only inserted if the far end of the MPLS tunnel is also entropy-label-capable. For more information, see the 7450 ESS, 7750 SR, 7950 XRS, and VSR MPLS Guide.
The hash label is configured using the hash-label command in the spoke-sdp context. Either the hash label or the entropy label can be configured on one object, but not both.
