<p>Hi Qianjiang<br>
<br>
We have create the external subnet and Router.<br>
the external subnet is ext_net.<br>
<img src="cid:part1.E07843CC.014D83FA@neusoft.com" alt=""
width="566" height="146"><br>
<br>
the Router is configured as below<br>
<img src="cid:part2.0A4A4401.F7B67D63@neusoft.com" alt=""
width="566" height="184"></p>
<p>the networking topology is as below</p>
<p><img src="cid:part3.DA328771.67BB3963@neusoft.com" alt=""
width="576" height="260"><br>
the CMD "ip netns list" is as below<br>
<img src="cid:part4.4AFC9941.3A81CF31@neusoft.com" alt=""></p>
<p>the external networking is 192.168.3.0/24, gateway is
192.168.3.3. it is our real networking for access internet. <br>
from 172.16.100.188(cirros-vm1) ping external subnet ext_<a
href="net:192.168.3.137">net:192.168.3.137</a> OK,<br>
from 172.16.100.188(cirros-vm1) ping 172.16.101.201 ((cirros-vm3))
is OK.<br>
from 172.16.100.188(cirros-vm1) ping 10.10.10.3 (controller-0) is
not OK.<br>
from 172.16.100.188(cirros-vm1) ping 192.168.3.106 is not OK.<br>
from 172.16.100.188(cirros-vm1) ping 8.8.8.8 is not OK.<br>
from 10.10.10.3 (controller-0) ping 8.8.8.8 is OK.<br>
from 10.10.10.3 (controller-0) ping 192.168.3.106 is OK.</p>
<p>But we can't connect external networking yet from cirros
instance, we will refer to</p>
