Read plugins/crd/validator/l2/l2_validator.go around lines 170-180 at commit c6ed55900e77dd14b8705dc6fa6d90f7a8b70b56, then inspect how vxLanBD is used after the loop. Determine whether taking &bdomain creates an unintended range-variable reference, and classify the finding as Bug, Mitigated, or Desirable Behavior with the requested reaction.
