BGP session resets
In the last 48 hours I have received several reports about different providers resetting or reloading ALL of their external BGP sessions due to problems. I have not heard why the ISP reset their sessions, or details of what the problem is/was. At first I just assumed it was normal maintenance activity. ISPs do reload their BGP sessions on a regular basis. But as additional reports are coming in, it doesn't seem to be normal maintenance. The resets are ISP network-wide, and happening outside of typical maintenance windows. I have reports four different ISPs needed to reset their BGP. A small number, and it may just be because people are watching things a bit closer than normal. Does anyone know why ISPs are doing this?
