When IPv6 is enabled on PPP profile (use-ipv6=yes + remote-ipv6-prefix-pool),
RADIUS-created dynamic simple queues become Invalid for active OpenVPN sessions.
RouterOS: 7.21.4 (long-term)
Protocol: OpenVPN + RADIUS (Mikrotik-Rate-Limit)
Steps:
- PPP profile: use-ipv6=yes, remote-ipv6-prefix-pool set, no scripts
- Client connects → dynamic queue created correctly
- IPv6 prefix assigned → queue becomes Invalid
- Cannot remove/edit: "can't remove dynamic object"
- Only reboot fixes it
IPv4-only profile: no issue.
IPv4 + IPv6 profile: Invalid queues accumulate, active users become unthrottled.
Expected: queue stays valid or is recreated after IPv6CP negotiation.
Actual: queue becomes Invalid and cannot be cleared without reboot.
