MLPPP QoS/MLFR QoS: Example

Because a bundle interface dynamically changes its bandwidth as the member links go up or down, QoS
policies applied on such interfaces need to be updated based on the bandwidth changes.
Step1: Two-Level Policy Applied to a Bundle Interface
For QoS, the bandwidth requirement is that the total of priority policing plus minimum guaranteed
bandwidth must be less than the total link bandwidth.
In this step, the MLPPP or MLFR bundle was initially applied with the following two-level policy and
had 10 T1 members when the policy was applied. When 10 T1 members are active, the bundle interface
bandwidth is 15,360 Mbps.
The child policy child_template1 is configured with a total of 13 Mbps for (priority policing and
minimum guaranteed bandwidth). It meets the bandwidth requirement.
