The answer for this task sets "frame-relay mincir 1536000", however in 8.1 we'd set "frame-relay cir 512000".
This raises two thoughts in my mind:
1. It doesn't make sense for the min-CIR to be greater than the configured CIR
2. Even if having a mincir > cir is valid, implementing this in this lab would break the requirement set in task 8.1, i.e. that the spokes have set CIR's and can only burst up to the access rate.
Am I missing something in my thinking?
