Dear All,
I am new to this, installed rocky on centos 7 with 2 node controller and
compute nodes, followed
https://docs.openstack.org/neutron/rocky/install/environment-networking-controller-rdo.html
as
mentioned in the document used vxlan and the Networking option 2: Self
service network and used linuxbridge, verified all the steps as
mentioned in the document and all things are working fine but i am unable
to access the internet in instances.
The network layout image attached herewith for reference there are two
ports, one is for management and another is a provider
network through which the internet is accessible.
The provider network is 10.1.0.0/16 and the gateway is 10.1.1.1 which I
have set in the external network..
When i run # ip netns command on controller node it shows qdhcp and qrouter
[root at controller ~]# ip netns
qrouter-2f84ff08-7293-4822-a4c1-57278d80f1cf (id: 2)
qdhcp-186cc689-267b-49ca-90a7-b312fd0367f3 (id: 1)
qdhcp-513292db-3eb8-4902-974f-4bb9c4757652 (id: 0)
but when I run # ip netns command on compute it shows nothing.
[root at controller ~]# openstack network agent list

+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+
Is there any need to create br-int or br-ex on nodes because that is not
mentioned in the link which i have followed, if need kindly guide the steps
to do that and on which node these steps need to follow.
