This also creates various issues as well as they lack a number
of BGP communities that are fairly standard across networks, so the
resulting behaviors can be rather inconsistent, or you end up with
traffic being long-hauled, even possibly off-continent due to scope.
I regularly see this behavior for prefixes behind HE, so be
aware you may actually not be seeing what you might naturally expect
unless you actually are looking closely.
If you just have 1-2 providers it may not be noticable, but the
larger the mix you deal with the more unexpected behaviors you can
quickly expose.
