I can't ping a loopback IP on one router from another router in GNS3

Hello Experts,

I have what I'm sure is a simple question.  I have two routers in GNS3.  The routers are connected using fa0/1.  I have configured R1 as follows:
!
Interface Loopback0
   Ip address 10.10.10.10 255.255.255.0

!
Interface FastEthernet0/1
   Ip address 10.1.1.1 255.255.255.252
   duplex auto
   speed auto

I have configured R2 as follows:

!
 Interface FastEthernet0/1
   Ip address 10.1.1.2 255.255.255.252
   duplex auto
   speed auto


At this point I can successfully ping 10.1.1.2 from R1 and 10.1.1.1 from R2.  However I cannot ping 10.10.10.10 from R2.  What am I missing?

Thanks
