Troubleshooting 6

Here we go with another simple but interesting troubleshooting scenario

Ensure that R1 can ping R2 and ensure any optimizations are retained.  Interfaces are in an up/up state and there are no ACL or security features restricting access. Some configuration and debug outputs are included below. Please provide a working configuration.


R1
__

R1(config)#do ping 10.0.0.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)


interface Serial1/0
 ip address 10.0.0.1 255.255.255.0
 load-interval 30
 serial restart-delay 0
end
