BIG-IP TMOS
Opened: Feb 22, 2022 Severity: 3-Major
Upgrading the BIG-IP from 15.1.6 to higher versions results in the error message "Can't load keyword definition (vlan.ipv6_prefix_len)" when loading the configuration.
The BIG-IP system will be unable to load its configuration and remain inoperative.
Upgrade from BIG-IP v15.1.6 or later in the v15.1.x branch to BIG-IP v16.1.2.2 or earlier in the v16.1.x branch.
This bug is known to be fixed in 16.1.3 and higher versions, So it is recommended to upgrade the BIG-IP to 16.1.3 version instead of 16.1.2.2
