This issue does not require any specific routing protocol to be configured or enabled.\n\nThe following commands can be used to monitor the DDoS protection queue:\n\n\u00a0 \u00a0 \u00a0 \u00a0labuser@re0> show evo-pfemand host pkt-stats\n\n\u2003\u2003\u00a0 labuser@re0> show host-path ddos all-policers\n\nThis issue affects Junos OS Evolved:\u00a0\n\n\n\n  *  All versions before 21.4R3-S8-EVO,\u00a0\n  *  from 22.2 before 22.2R3-S4-EVO,\u00a0\n  *  from 22.3 before 22.3R3-S4-EVO,\u00a0\n  *  from 22.4 before 22.4R3-S3-EVO,\u00a0\n  *  from 23.2 before 23.2R2-EVO,\u00a0\n  *  from 23.4 before 23.4R1-S1-EVO, 23.4R2-EVO,\u00a0\n  *  from 24.2 before 24.2R2-EVO."
