One has the same issue in IOS XR, where BGP communities are only

Thanks again, Mark.
So I guess the short answer is that I can't infer anything about the
location of physical connectivity having this level of information from the
control plane. Is that a fair statement? What if the Next Hop is inside
the neighbor AS. I know it is a rather odd and uncommon

I know for example the router is in, say LA. If hot potato lets me to send
the packet to the neighbor AS then they have an AS connection in LA, right?
Going back to my example does the fact that the entry does not have 'i'
Thanks Mark for the reply. Let me try to check what I understood is
correct. Does the 'i' on the left (status code) only shows whether the
prefix belongs to this AS?
What I want to figure out is if this two ASes (the owner of the router and
and the first one on the AS-PATH) connect at the

Status-code i just means the entry was learned by this router via
