    description
        "This module provides mapping between SRV6 locator identifiers
         defined in the ietf-nat-srv6-base module
         and identifiers used by the VPP SRV6 plugin.

         The mapping is managed internally by the HC SRV6 plugin.
         It is exposed as operational state data for debugging purposes.
