Just a quick followup regarding my earlier post.
To influence OUTBOUND traffic to the internet to take one router over another (regardless of which router the traffic came in) I would tweak BGP preferences such as local pref, metric, etc using route maps and such.
Is that a fair summarization and grasp of the concept?

Also, some providers allow you to tweak your announcements to them by
setting BGP communities. We do this by allowing customers to set their
local_pref to one of 3 values (customer preference, peer preference, below
peer preference). Of course, this only helps if you have multiple prefixes
to announce, which may or may not be the case. Some providers also will
have standard routing services like the ability to send only that providers
customer prefixes. Asking your provider what services they offer is
probably a good start.
