Hello all,

Our company has two offices in two separate buildings and we have a lease line connecting the two offices. The line and both routers on each end of the line were fine for the last 6 months but recently I noticed on our Network Monitoring Tool that the router on one end drops packets or it is unreachable but after 3 to 5 seconds everything resumes back to normal.

What might be the cause? How can you advise me to scrutinize this situation?

Looking forward for your comments.

Thanks,
