We use one router (x86 ) as an aggregate and on it we follow all traffic.
Make also NAT and Firewall.
Simple queue use in tree mode, in top of the tree, first level is global queue, its parent for all segment queue, with limit of maximum internet capacity like 1024Mbps.
In the second level is segment queue like 10.1.1.0/24 with no limit.
And last level is end user limiting inside the segment queue, like 10.1.1.50 with limit 15Mbps.
If this all queue turn on, lose IP traffic to internal network. To internet is ok. In my case, on this router LAN port have 10.1.250.2/24 and dont ping any other router in backbone. But In neighbors I see this routers.
I try 6rc6, 6rc8, 6rc13, 6rc14, result is same. In older 6 we have problem with kernel panic. In ROS 5.x have unexpectex reboot in 3-10 days. Last functional queue was in 4.17, but dont support new hardware.
Queue export in attachments.
Thanx for help
