Responsible and overall best: connect to the same 2+ providers in both locations and announce more specifics locally in each region/city/whatever with no-export.As said above, this isn't possible. I'd like to learn what could be done in this kind of situation that would allow the desired redundancy, while also being responsible. I'm not a manager of a large network (where I might have this kind of problem myself), nor am I employed at a large ISP (where my customers might have this kind of problem). But I would like to learn.
It depends on the quality of intra-AS connectivity. In situations such as Ralph's, where intra-AS connectivity is strong, it has been shown that there is a technique to allow for the weaker transit link to be only used for backup: conditional BGP announcements and a gre tunnel over the transit links in both cities.
