The rpd crash occurs before the update can be readvertised, so there is no downstream propagation.\n\n\nThis issue affects:\n\n\n\n  *  Junos OS versions 25.2 before 25.2R2;\n\n\n  *  Junos OS Evolved versions 25.2 before 25.2R2-EVO.\n\n\n\n\nThis issue doesn\u0027t affect Junos OS versions before 25.2R1 nor Junos OS Evolved versions before 25.2R1-EVO."
