Junos OS:
- all versions before 21.2R3-S7,
- from 21.4 before 21.4R3-S5,
- from 22.1 before 22.1R3-S5,
- from 22.2 before 22.2R3-S3,
- from 22.3 before 22.3R3-S2,
- from 22.4 before 22.4R3,
- from 23.2 before 23.2R1-S2.
Junos OS Evolved:
- all versions before 21.2R3-S7-EVO,
- from 21.3 before 21.3R3-S5-EVO,
