R2 # neighbor 12.0.0.1 remote-as 5500
R2 # neighbor 23.0.0.3 remote-as 6500


R3 # int s0/0
R3 # ip add 23.0.0.3/24

Because when you ping from R1, you are sourcing your ping with 12.0.0.1.  R3 does not have a route to the 12.0.0.0/24 subnet so the ICMP reply fails. You need to put the 12.0.0.0/24 subnet in BGP whether via redistribute connected on R1 or via network statement.
