ISP Ping Test Unsuccessful

[Aaron John]

I had set up and configured a small office network using cisco packet tracer (File Attached). The network included two subnets for different departments: Admin and Employee, with internet access provided by an ISP, that is 

1. 1 Router (e.g., Cisco 2911).
2. 1 Switch (e.g., Cisco 2960).
3. 4 PCs:
• Two PCs in the Admin subnet (192.168.10.0/24).
• Two PCs in the Employee subnet (192.168.20.0/24).
  1 ISP Router (to simulate internet access) 

As I checked the connection by ping Only the ISP Router failed to communicate with 100% loss. Can I have a solution to this?

@Aaron John hi,

in ISP router

1. remove 2 sub interfaces Gi0/0.10 and Gi 0/0.20. then add static routes as below.

2. 

Router(config)#ip route 192.168.10.0 255.255.255.0 203.0.113.2

Router(config)#ip route 192.168.20.0 255.255.255.0 203.0.113.2
