VPN Troubleshooting

Hello, as part of my preparation for CCNA Security I've been making up my own topologies and configuring them, however, I need a little help with this one. In the topology (included .pka), I configured VLANs, Port Security, OSPF, OSPF Authentication and  everything worked fine until I configured the VPN. When I try ping PC2-PC3 or PC2-R2 for example, which generates "not interesting traffic" it still works, however when I try to ping PC2-PC1, traffic is unable to get through R1. 

Error message: 

The interesting traffic can not be encrypted, IKE (ISAKMP) needs to negotatiate IPSec SAs



Any help is appreciated.
Thanks.
