[Starlingx-discuss] 【StarlingX】Regarding external networking issue

[付勇]

Hi StarlingX team

we have deploy virtual All-in-one simplex machine and have a question to ask for help.

 

1. problem:

we met a problem with how to connect the external networking in cirros or centos instance.

 

2. current status

controller-0 IP: 10.10.10.3

cirros-vm1 IP: 172.16.100.188,

from 172.16.100.188(cirros-vm1) ping external subnet

ext_net:10.10.10.190 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 8.8.8.8 is not OK.

from 10.10.10.3 (controller-0) ping 8.8.8.8 is OK.

 

3. configuration

(1) ml2_conf.ini

in container: neutron-ovs-agent-controller-0-937646f6-dtqcn: 

/etc/neutron/plugins/ml2/ml2_conf.ini

-----------[file:ml2_conf.ini]--[begin]----------

[agent]

extensions =

[ml2]

extension_drivers = port_security

mechanism_drivers = openvswitch,sriovnicswitch,l2population

path_mtu = 0

physical_network_mtus = physnet0:1500,physnet1:1500 tenant_network_types = vlan,vxlan type_drivers = flat,vlan,vxlan [ml2_type_flat] flat_networks = [ml2_type_vxlan] vni_ranges = vxlan_group = [ovs_driver] vhost_user_enabled = true [securitygroup] firewall_driver = openvswitch

-----------[file:ml2_conf.ini]--[end]----------

 

(2) the networking topology refer below pic or the attached file.



 

4.infer:

we need to create a bridge to connect with the external subnet with the external networking.

 

5.requirement:

We want to ask how to configure to connect external networking in cirros-vm1 or centos instance?

we expect result as below:

from 172.16.100.188(cirros-vm1) ping 8.8.8.8 is OK.

 

Best Regards

Wish you happy everyday!
