[ee122] HW Problem 2-> (4.29)

I don't quite understand this question, with respect to the fact that
it says "Suppose eBGP and iBGP are used for inter-AS routing." iBGP is
for intra-AS routing sessions... so why would it be used for talking
to another AS?

Furthermore, let's say some AS was running OSPF (as in the problem)
and the border router was using eBGP to speak to other AS border
routers. Would the border router speak to its network in iBGP, only
its neighbor router in iBGP or none (since the AS is defined as OSPF)
at all? I'm confused because when the book talks about routing
protocols, all the routers in the example use the same protocol, with
no mixing...

Any hints or clarifications would be helpful. I've skimmed/read the
routing protocols from the book a couple times and also read the
slodes on BGP, but nothing really talks about gateway/intra-AS
