Can we find a way to enhance BGP stability when we are running on reduced IMA bandwidth.
Our router has 3xT1 IMA, when all 3 T1s are running properly, we have no problems. When a Layer 1 issue occurs on one of the T1s (reduced bandwidth) then the router becomes highly unstable (BGP timeouts/flapping). BGP flaps continuously when we lose a T1, and then the service is unavailable.
Is there a way to create a policy map that will give BGP priority, so we will not experience an "outage" during a layer 1 issue? In other words, BGP will get a level of priority to insure it does not FLAP continuously.
