If your routes are being passed to an IBGP neighbor from an EBGP neighbor,
the next hop attribute remains the IP address that the EBGP neighbor is
configured to send. If your IBGP neighbor does not know how to get to this
address, the routes will never get installed. When you do the next-hop-self
command, the router sends the update with itself as the next hop to the
neighbor for which it is configured, so you are probably seeing a case where
your internal router does not know how to get to the next hop of the EBGP
routes, but when you give the next hop self command on the upstream router
it can now get to the next hop and so installs the routes.
