I have ran into this a few times, and have not found a solution:
=20
L3 =E0=20
HE=E0 --- blended Provider A --- > Customer
=20
Cogent -- > Customer
=20
Cogent of course is cheaper, and customer wishes to use the blended =
provder more as backup and/or have most of the inbound traffic coming in =
the cheaper path (cogent). The issue appears to be L3 and HE =
specifically (of course they make up a good chunk of inbound traffic) =
always prefers their customer peers, so even if we advertise any prefix =
to the blended, those companies (l3/he) always choose to come in though =
the customer peer and then to my customer.
=20
Any thoughts on how to get around this, and still have some kind of =
route in the blended provider for failover? Off list is fine.. Thanks =
in advance. =20
