Im testing out VIRL images on gns3 so my first test was to have 2 routers on the same subnet and have them ping each other. For some reason they wont ping each other but when i place two 2691 routers with the same configs as the other routers they ping perfectly fine. Below is the config for the CiscoIOSv15.6(2)T Routers the only difference is the ip address.
Escape character is '^]'.
