Re: 1 Mbps ATM PVC running BGP
First thing I would check is traffic-shaping parameters. Ask your ISP for _exact_ shaping specs for your PVC. If there is a mismatch on either side, one of you will drop cells. Once a single cell drops, you start re-transmitting entire packets... Then you might drop a cell from the re-transmitted packet. basically all hell breaks loose.

Re: 1 Mbps ATM PVC running BGP
RE: 1 Mbps ATM PVC running BGP It could be, I'll check about MTU. Yes, we do rate-limit on both side . the funny thing is after we = established BGP, we only receive 1 BGP routing although on the other = side sent all their BGP routing. And after 3 minutes, the BGP session is = closed by itself and then go up again for only 3 minutes.
