Hi, I'm interested in how folks implement max-reserved-bandwidth with their qos(strict priority/CBWFQ/etc.)
any help is appreciated
Yes, default class should be working.
On many Cisco routers, bandwidth in the default class configures a FIFO queue. Without it, normal default is flow based fair-queue. Also on most routers, default class flow queues compete for bandwidth with defined classes. However, the LLQ, when there's congestion, preempts all the other queues (up to its defined cap).
