right now this is our current BGP config. we have two class C's and two ISP's. we would like both networks to prefer the Verizon path for inbound over ATT while we do maintenance on the ATT circuit and would like some advice on the best way of doing this. thank you

    I think that's AS702, not AS7020. – Teun Vink Dec 8 '15 at 22:05

Shut down your BGP session with ATT and wait a few minutes for BGP to converge globally, that should do the trick.

  • Or mark your announcements to ATT "no-export", so they apply only to things within their AS. – Ricky Dec 9 '15 at 2:19
