I have router A connecting to ISP A and router B connecting to ISP B.
I have 2 routers (prefixes) to be advertised.
Under normal conditions, I want to have prefix A advertised to ISP A only and prefix B advertised to ISP B only.
If router A or ISP A should fail, I want router B to advertise prefix A to ISP B (and vice versa).
I am receiving only a default route from both ISPs.
I can make this work if I had only 1 router using BGP conditional advertisement, but I can't figure out how to make it work with 2 routers. Any ideas?
