Configuration of GRE

1)Show the status of designated tunnel interface. Quidway# show interface tunnel 1

Tunnel1 is up, line protocol is up Internet address is 3.1.1.1 255.255.255.0 10 packets input, 640 bytes

0 input errors, 0 broadcast, 0 drops

10 packets output, 640 bytes

0 output errors, 0 broadcast, 0 no protocol

The above information means that: The network address of “Tunnel1” is 3.1.1.1. 0 message is received. The number of received error message and broadcast message is 0. There is no discarded message. The number of transmitted messages is 0. There is no the message with error output, the broadcast message and the message with unknown protocol type

2)Show router table of the system. Quidway(config)# show ip route
