505050 is being learned via IPX EIGRP accross the tunnel. You are running
EIGRP between both tunnels on 606060, and all the network information from
R1 is learned to R4 over that link. Just because you enabled NLSP on
505050 doesn't mean its not going to create routes in EIGRP. If you don't
want it to flow accross on EIGRP then filter it out with a distribute
list.
