hmmm notice that all of these /24's are from ^_8001_ which peers with
route-views.oregon-ix.net which may from time to time include internal
iBGP prefixes that are otherwise not advertised to regular transits/peers,
to their way of making to GRT.

What you pasted is what route-views.oregon-ix.net sees. What I see is:
