Monika, If it's every 3 minutes or so, you are experiencing a router pruning issue. This usually occurs when your outgoing traffic takes a different path than the incoming traffic. The routers don't see any acknowledgement on the primary path so it prunes the route. Three minutes later it gets reestablished. We found this here in Utah. Our outgoing traffic used I2 and the incoming traffic came through NLR. We had to block the traffic on NLR to fix this. You'll need to get your network staff involved.
