I have a T-1 from ISP-A and a DS3 from ISP-B and advertising my class C network block 192.168.1.0/24 (changed) to both ISPs. I want ISP-B to be preferred for inbound traffic for which I have appended my ASN 5 times on ISP-A. But the problem here is that ISP-B is advertising a 192.168.0.0/21 out to thier peers. And if the DS3 goes down, there will be a routing loop. Please advice.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
