hi
You are making ibgp neighborship. So you donot requite the ebgp-multihop
command.With thsi also remore inbound soft reconfiguration because it will
simply use your bgp process.
One more thing which we come to know from the debug that the problem is just
because of media. So please check your media.
regards
