BGP next-hop self


Hi everyone, I have configured eBGP and iBGP. I used next-hop self in R2. but now I can see that in the routing table of R1 there is no route to 20.1.1.0. my question is is there a way that from R1 I can ping the loopback address of R1 which is 200.1.1.1. Loopback 0 is used for testing.

thanks.
