Hi Folks,
I have 2 routers and 2 Laptops. An 1841 and 887 Cisco Router. As per the attached diagram, I have the following config:
Config (887) - 192.168.0.0/24:
Router(config): vlan 10
Router(vlan 10): inter vlan 10
Router(vlan-if): ip address 192.168.0.254 255.255.255.0
Router(vlan-if): no shut
Router(config):int fa0/0
Router(config-if):switchport mode access
Router(config-if):switchport access vlan 10
Router(config): vlan 20
Router(vlan 10): inter vlan 20
Router(vlan-if): ip address 192.168.1.1 255.255.255.252
Router(vlan-if): no shut
Router(config):int fa0/1
Router(config-if):switchport mode access
Router(config-if):switchport access vlan 20
Router(config): ip route 172.16.0.0 255.255.0.0 192.168.1.2
Config (1841)-172.16.0.0/16:
Router(config): int fa0/0
Router(config-if): ip address 172.16.0.254 255.255.0.0
Router(config-if):no shut
Router(config):int fa0/1
Router(config-if):ip address 192.168.1.2 255.255.255.252
Router(config-if):no shut
Router(config):ip route 192.168.0.0 255.255.255.0 192.168.1.1
Laptop IP for 1841: 172.16.0.1 255.255.0.0
Laptop IP for 887: 192.168.0.1 255.255.255.0
Now, i can ping from (887) 192.168.0.1(Laptop) to DG(192.168.0.254) and i can ping to 192.168.1.1,192.168.1.2 (both hops). I can also ping 172.16.0.254 (DG for 172.16.0.0/16) and 172.16.0.1.
I can ping from 172.16.0.1(Laptop) to 172.16.0.254(DG) & can ping to 192.168.1.2, 192.168.1.1 (both hops) and I can ping till 192.168.0.254 (DG for 192.168.0.0/24). When i ping 192.168.0.1, it fails.
Everything works except the Laptop for 192.168.0.1. Why does it fail?
Any ideas and advise?

i do not see any reason here, check on end device have any FW ? is this simulated lab ?

No. This is on physical devices, not simulated lab. The attachment is just the design i posted for better understanding.

the pic do not show how you configured in the device, it will give logical understanding.
as per the pic it should work, but it was not, hence this post ?
to guide in correct way like to see configuration.

I agree with BB that the most likely explanation is that there is some firewall or security policy on the PC that rejects attempts to ping. As a test of this I suggest that from the 887 router trying to ping the connected PC. I suspect that it will fail and that certainly would point to some issue on the PC.
