We have dual-homed BGP, with AT&T and Sprint, with links from ISP terminating on different
We also have different network blocks from each ISP, let's say block A, B, & C from ATT
and block X, Y, & Z from Sprint.
What we like to do, is if traffic is sourced from A/B/C, we always want to send it out to
ATT and if traffic is sourced from X/Y/Z, it is always sent to Sprint - as long as links
to ISP is up.
How can I do this using BGP?
