Hi Qianjiang
We have create the external subnet and Router.
the external subnet is ext_net.
the Router is configured as below
the networking topology is as below
the CMD "ip netns list" is as below
the external networking is 192.168.3.0/24, gateway is 192.168.3.3. it is
our real networking for access internet.
from 172.16.100.188(cirros-vm1) ping external subnet
ext_net:192.168.3.137 OK,
from 172.16.100.188(cirros-vm1) ping 172.16.101.201 ((cirros-vm3)) is OK.
from 172.16.100.188(cirros-vm1) ping 10.10.10.3 (controller-0) is not OK.
from 172.16.100.188(cirros-vm1) ping 192.168.3.106 is not OK.
from 172.16.100.188(cirros-vm1) ping 8.8.8.8 is not OK.
from 10.10.10.3 (controller-0) ping 8.8.8.8 is OK.
from 10.10.10.3 (controller-0) ping 192.168.3.106 is OK.
But we can't connect external networking yet from cirros instance, we
will refer to
/>>>>>
/
/There are some check point :/
////
/Which NIC ext-net is connected ? /
//
/Which bridge this NIC is connected to on host ? /
//
/Does this bridge config ip address (should be 192.168.3.1)?/
//
/And have you config any security group to enable icmp ? /
//
Thanks.
BR
Austin Sun.
/>>>>/
we will share our progress if any result.
Thanks&Best Regards
