Dear WG,

I submmited a new version of draft-peng-pce-entropy-label-position-06. This draft proposes the extensions for PCEP to configure the entropy label positions in SR-MPLS networks as described in RFC8662. Multiple EL/ELI pairs may be inserted in the label stack and the inserted positions SHOULD be whithin the ERLD of a maximize  number of transit LSRs.

This draft is useful and reasonable for two use cases as following shown.
1, For intra-domain scenario, the ingress node need to evaluate the minimum  ERLD value along the node segment path.  But it will add complexity in the ELI/EL insertion process. The ingress nose can get the path minimum ERLD from PCE and perform the insertion of ELI/ELs based on the minimum ERLD value.
2, For inter-domain scenario, the ingress node of the first domain cannot  find the minimum ERLD along the path and does not support the computation of the minimum ERLD.The PCE can compute the  Entropy Label Position  including the number and the places of  the ELI/ELs.

Any comments and suggestions are appreciated!
