/24 covers the whole range of ip in the last octet, but /29 covers part of it as well.
This will always result in overlap if you try to configure those on the same router.
I recommend you join the ccent and ccna forums for help...also you need a good study book to review ip subnetting.

This little exercise may help you understand routing
1. Say Hani is data sitting in his living room (network) 10.0.0.1/24 which is 10.0.0.---something--- 1 to 255
2. And he wants to go to the kitchen (network) 10.0.1.1/24 which is 10.0.1.---something--- 1 to 255
3. Now the route or exit you take to leave the living room has a number above it, this would be s0/0/0 10.0.0.2 mask 255.255.255.0
4. Now you are inside hallway leading to the kitchen (This is a router)
5. To get to the kitchen (that other network) you need exit s0/0/1 and it needs to be a different network 10.0.1.2 mask 255.255.255.0.
6. What you tried to do with your question was “leave” or “route” the network 10.0.0.1.
7. But, the destination you were headed to was 10.0.0.2, which is the same network.
8. SO, you wanted to leave the living room, walk through the hallway, until you reached the living room.
9. This is your overlap error
If you had 2 routers, then it would have been okay to have routerA fa0/0 10.0.0.1 and routerB fa0/0 10.0.0.2 and both with a fa0/1 as 10.0.0.3 (connecting them together)
1. Now the route can be completed by leaving through routerA
2. Moving from routerA to routerB
3. Then returning by means of routerB
Thanks all for help i really do appreicated it
I figured out the problem
I have to delete all networks with the same subnet in all interfaces so i would able to set network range for example /30 if i want to set network for 2 available hosts in two direct connected routers but i cannot have /24 on interface and another interface /30
You can have /24 & /30 on same router but the network address of both networks must not be same. As router is a layer 3 device it connects 2 different networks. so 2 ports of a router cannot be in same network.
