This will cause the respective FPC to stop forwarding traffic and it needs to be rebooted to restore the service.\n\nAn indication that the system experienced this issue is the following log message:\n\n\u00a0 <date> <hostname> evo-aftmand-bt[<pid>]: [Error] jexpr_fdb: sanity check failed, ... , app_name L3 Mcast Routes\n\n\n\n\nThis issue affects Juniper Networks Junos OS Evolved on PTX10001-36MR, PTX10004, PTX10008, PTX10016 with LC1201/1202:\n21.2 version 21.2R1-EVO and later versions;\n21.3 version 21.3R1-EVO and later versions;\n21.4 versions prior to 21.4R3-S3-EVO;\n22.1 version 22.1R1-EVO and later versions;\n22.2 versions prior to 22.2R3-S2-EVO;\n22.3 versions prior to 22.3R3-EVO;\n22.4 versions prior to 22.4R1-S2-EVO, 22.4R2-EVO.\n\n\n\n"
