Hi, 4 routers (R1,R2,R3,R4) connected via FR cloud. 2 of the routers (R1,R2) have GRE trunnel with no ipsec. R1 has router id 4.4.4.4/32. R2 has router id 3.3.3.3/32. OSPF v2 running. R1-R2 Area3, R2-R3 ARea 0, R3-R4 Area 12.
R1 is connected to L3 Switch. in between L3 switch and R1 is EIGRP AS 1. I have redistributed the EIGRP, OSP on R1. Show ip route at R1 as below

I am bit worried about the logical link 4.4.4.4 which is appearing as connected and through EIGRP. I have checked in L3 switch I havent configured any route 4.0.0.0/8. please advise.
