Due to this issue, the router will start forwarding traffic if a valid route is present in forwarding-table, causing a loop and congestion in the downstream layer-2 domain connected to the device.\n\nThis issue affects Juniper Networks Junos OS Evolved on PTX10001, PTX10004, PTX10008, and PTX10016:\n\n\n\n  *  All versions prior to 21.4R3-S5-EVO;\n  *  22.1 versions prior to 22.1R3-S4-EVO;\n  *  22.2 versions 22.2R1-EVO and later;\n  *  22.3 versions prior to 22.3R2-S2-EVO, 22.3R3-S1-EVO;\n  *  22.4 versions prior to 22.4R2-S1-EVO, 22.4R3-EVO;\n  *  23.2 versions prior to 23.2R1-S1-EVO, 23.2R2-EVO.\n\n\n\n\n\n\n"
