Does anyone understand why the far end of a Mutlilink interface would stay up but stop responding to a ping _for_approx_60_secs_ when any of the individual T1 interfaces in the bundle go down? The near end, the Multi2 interface on the 7200, continues to respond to a ping the entire time. The output of "sh int multi2" indicates that packets are flowing out and IN but I'm not able to ping several hosts (all i tried) at the far end.
Here's a sanitized copy of the config which hasn't changed recently.
