So basically you have configured a transit network with an internal router not
participating in the IBGP full mesh. I assume you've read somewhere that this
doesn't work well :) Full mesh is a requirement. You _could_ redistribute you
r BGP into OSPF which is nasty, or add some defaults to R2 which could be loopy
, or properly configure the IBGP full mesh.
