Router on a stick not working

Hi guys, I have a problem with the router on a stick. I am trying to ping from R1 to S1 interface 192.168.1.2. But ping does not work. I have doubled the basis IP configuration for R1 and S1. There is no typo error so far. The address 192.168.1.2 is in the router table which is beyond to [C 192.168.1.0/26 is directly connected, GigabitEthernet0/0/1.100]. Can anyone help? Thanks

R1 Router Table

Gateway of last resort is 10.0.0.2 to network 0.0.0.0

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C 10.0.0.0/30 is directly connected, GigabitEthernet0/0/0

L 10.0.0.1/32 is directly connected, GigabitEthernet0/0/0

192.168.1.0/24 is variably subnetted, 4 subnets, 3 masks

C 192.168.1.0/26 is directly connected, GigabitEthernet0/0/1.100

L 192.168.1.1/32 is directly connected, GigabitEthernet0/0/1.100

C 192.168.1.64/27 is directly connected, GigabitEthernet0/0/1.200

L 192.168.1.65/32 is directly connected, GigabitEthernet0/0/1.200

S* 0.0.0.0/0 [1/0] via 10.0.0.2

Hello, 

You have a few things going on to start:

1- R1 has 192.168.1.1 with a /26 mask and S1 has 192.168.1.2 with a /27 mask. Need to have the same masks.

2- In R1 192.168.1.1 is in VLAN 100 and on S1 192.168.1.2 is in VLAN 1. Need to fix that.

3- Make the trunk's native VLAN 200 on R1 and S1.

4- Remove the

ip route 192.168.1.0 255.255.255.192 GigabitEthernet0/0/1

it serves no purpose and as a rule you cannot point a static route to an ethernet interface. It has to point to an IP.

Hope this helps

Thanks for your help. I changed 192.168.1.2 from VLAN 1 to VLAN 100 on S1 without changing the mask and the problem was solved.
