Help on OSPF protocol

hey guys,
I set OSPF on routers and all devices can ping each other Except “Router 101”. It just can ping other routers which have 10.10.70.0/24 IP, but RT101 and computers can not ping each other.
what is the problem?

    Hello geforce1010,

    Can you, please, provide a tracert from any host (PC, Laptops) to Router 101?

    And, when you did your tracert, it might stop on one router.
    From this router, can you provide us the output of the "show ip route" command?

    Did Router101 learn routes for the subnets in area 2 ? As ITsubced mentioned I would like to see the routing table for RT101.

    Thank you both. I added an IP to another interface of RT101 (fa0/1) and the the problem solved! then again I shut the fa0/1 down and remove IP from it and ROUTER OSPF, but the RT101 can ping all PCs now!!! I don't know what the problem was!
