Where-next-hop-self

Hi, all:

A case says the next hop to 172.16.0.0 in Ra should be the 1.1.1.2 in the topology:

Ra(spoke)------FR--------Rb(hub)-------FR-------Rc(spoke)
1.1.1.1-----------------1.1.1.2-----------------1.1.1.3---172.16.0.0
As1----------------------As2--------------------As2

It says the next-hop attribute has been carried by Rb to Ra, to prevent 1.1.1.3(next-hop) being seen, the command "neighbor 1.1.1.1 next-hop-self" must be under "router bgp 2" on Rb. My thought is the 3 routers are in the same subnet, so its unnecessary to change the default next-hop. Any advice?

TIA
dillon
