Local preference, eh? Sounds like the architect has to be a real *preference* whisperer to get this one right. Haha, get it? Preference? Ah, never mind, I'll see myself out.

Ah, the old BGP routing dance. I'd say D is the way to go here. Setting the local pref high is the best way to ensure that traffic takes the desired path. Plus, it's less likely to cause any unintended consequences down the line.

I think setting a higher local preference is the most reliable option.

But what about prepending additional AS on the AS path?

I'm not sure about this one. Breaking the routes into longer prefixes seems a bit hacky, and prepending ASes could get messy. I think D is the cleanest solution, but I'd double-check the configuration just to be safe.

But wouldn't it also be effective to prepend additional AS on the AS path toward the preferred service provider?

Hmm, the answer seems pretty straightforward. I'd go with D, setting a higher local preference to the preferred service provider path. That's the most direct way to influence the BGP decision process.
