Guys,
Few days ago our Primary ISP had an issue in one NIC of its Core Routers. Due to that we started receiving packet loss (50%) and VPN point-to-point tunnels bouncing. In our environment the solution was shutdown MANUALLY the interface (which is our PRIMARY BGP peer connection) facing the PRIMARY ISP. After that the whole internet traffic started going back and forth using the BACKUP lSP.
With that been said, we would like to fine a solution that provide us the same final result (shutdown the interface facing the PRIMARY ISP), but the automatically.
I have read about IP SLA and EMM, but even when I think I'm so closed, I'm not.
Let say: The internet router would check (launching PINGs) one or two resources on the internet and it will compare the amount of packet loss (in %). In the case this amount exceeds a predefined threshold (50%), I would like to automatically do one or the other option:
1.- Shutdown the BGP neighborhood with my Primary ISP. keep checking... If the packet loss FINISHED, re-establish the BGP neighborhood/session.
2.- Shutdown the interface in front of the Primary ISP.
Any thoughts ?
thank you,
