The above output shows that no available route exists between Firewall and Device B; an available router

exists between Firewall and Device A; an error occurred on the connection between Device A and Device

B. In this case, you can use the debugging ip icmp command to enable ICMP debugging on Firewall and

Device B to check whether the devices send or receive the specified ICMP packets, or you can use the

display ip routing-table command to display whether a route exists between the two devices.
