Hi there,

Hope you networking experts can shed some light on a concern I have please. I am multihoming using 2 ISPs to the internet, due to reasons outside my control, my primary preferred link keeps dropping a number of times a day forcing traffic to my backup and vice-versa when the primary comes back up.

The route calculations by the upstream tier 1s and 2s handle the route calculations but if I do this too many times consuming their resources, is there a penalty/blackmark on my AS? Is this monitored even by the tier1s and 2s?

Thanks.

Regards,
Gus C.
