VPCS 2 >ip 40.0.0.2 40.0.0.1 8
VPCS 2 >3
VPCS 3 >ip 50.0.0.2 50.0.0.1 8
VPCS 3 >show
VPCS 3 >ping 40.0.0.2
40.0.0.2 icmp_seq=1 timeout
40.0.0.2 icmp_seq=2 time=94.000 ms
40.0.0.2 icmp_seq=3 time=125.000 ms
40.0.0.2 icmp_seq=4 time=94.000 ms
40.0.0.2 icmp_seq=5 time=110.000 ms
VPCS 3 >ping 30.0.0.2
30.0.0.2 icmp_seq=1 timeout
30.0.0.2 icmp_seq=2 time=125.000 ms
30.0.0.2 icmp_seq=3 time=125.000 ms
30.0.0.2 icmp_seq=4 time=156.000 ms
30.0.0.2 icmp_seq=5 time=156.000 ms
VPCS 3 >1
VPCS 1 >ping 40.0.0.2
40.0.0.2 icmp_seq=1 time=94.000 ms
40.0.0.2 icmp_seq=2 time=93.000 ms
40.0.0.2 icmp_seq=3 time=94.000 ms
40.0.0.2 icmp_seq=4 time=94.000 ms
40.0.0.2 icmp_seq=5 time=141.000 ms
OK   完成!!!
