With ibgp there is no need for multihop. You can already peer with
ibgp on for example the loopbacks without any special config (besides
setting the update-source). Just needs an underlying igp route!
For the other protocols, if not using a tunnel, you would have to find
a way to establish an adjacency without broadcasting/multicasting. So
that would mean:
RIP: passive-interface default + neighbor x.x.x.x
OSPF: ip ospf network-type nonbroadcast + neighbor x.x.x.x
EIGRP: neighbor x.x.x.x <outgoing intf>
