    Can any one tell me what would happen if you have class of service
    configured on a bundled IMA circuit (two T1's) and you lose one of the
    physical circuits, how does your QoS configuration treat that?

    i.e. You have a class of traffic that is configured to use 60% of your
    circuit (based on the 3Mb of the IMA configuration) and you lose a T1.
    60% ends up being about 1.8Mb, which would then saturate your remaining
    T1 - is this right, or does the router realize it has lost a circuit
    and compensate?

  2. The router does recognize the lost circuit if OAM is enabled..
    Otherwise it wont..
