Dynamic Simple Queue

RouterOS General
1

Hello,

I’m working in ISP, and we have a lot of Mikrotik devices.
A huge problem for us is that we can no more delete dynamic simple queue from version 7.5.
We use a script to prioritize traffic for pppoe clients.
Among other things, the script creates static parent queues, child queues and should delete dynamic queues at the end.
Unfortunately, it no longer works after 7.5 version, because dynamic queues cannot be deleted.
Can you, Mikrotik Team, bring that feature back again, please?

Hi,
I am also facing the same issue, and am unable to delete the Dynamic Simple Queue after upgrading the RB.
Any solution?

Hi,

It’s August 2025 outside the office but the issue is still there. Dear Mikrotik support, will it ever be fixed or we have just to live with it?

Kind regards,

R

Subject: Dynamic Simple Queue becomes Invalid during PPP IPv6CP negotiation (RouterOS 7.x)

RouterOS version: 7.21.4 (long-term), also reproduced on 7.15.3, 7.9.2
Hardware: CHR (VMware), x86
Setup: OpenVPN server with RADIUS authentication and Mikrotik-Rate-Limit

--- Description ---

When a PPP/OVPN session has both IPv4 and IPv6 enabled on its profile
(use-ipv6=yes, remote-ipv6-prefix-pool set), the dynamic simple queue
created by RADIUS Mikrotik-Rate-Limit becomes Invalid while the session
is still active.

This does NOT happen with IPv4-only profiles. Adding use-ipv6=yes and
a prefix pool to the profile is sufficient to trigger the issue — no
on-up/on-down scripts are involved.

--- Steps to reproduce ---

  1. Configure an OVPN server with RADIUS authentication.
  2. RADIUS returns Mikrotik-Rate-Limit (e.g. 10M/10M).
  3. Set PPP profile: use-ipv6=yes, remote-ipv6-prefix-pool=,
    remote-ipv6-prefix-reuse=no, on-up="", on-down="".
  4. Connect a client. A dynamic simple queue is created correctly.
  5. Within minutes, as clients reconnect or IPv6CP renegotiates,
    dynamic queues accumulate with the Invalid (I) flag.
  6. The queues cannot be removed (can't remove dynamic object),
    disabled (can't edit dynamic object), or modified in any way.
  7. Only a full router reboot clears them.

--- Expected behavior ---

Dynamic simple queues should be removed automatically when the PPP
session that created them ends or renegotiates. This worked correctly
in RouterOS 6.x.

--- Actual behavior ---

Queues are not removed on session end/renegotiate. They accumulate as
Invalid entries. After hundreds of reconnects, the queue list becomes
unusable. Active sessions with Invalid queues are no longer rate-limited,
causing some users to exceed their assigned bandwidth.

--- Impact ---

Any ISP using RADIUS Mikrotik-Rate-Limit + IPv6 on PPP/OVPN profiles
on RouterOS 7.5+ is affected. The only workaround is to either reboot
periodically or stop using Mikrotik-Rate-Limit entirely.
