Maybe. Like, get a router, which has a BGP config. And then *show*
that to us.
BGP has no problem in redistribution eBGP-iBGP-eBGP - actually, this is
the normal behaviour, unless you have filters in place to prevent that.
BGP will never(*) do redistribution eBGP-iBGP-iBGP, though, so depending
if your setup has multiple iBGP links in sequence, this will prevent
prefix propagation.
