So im trying to understand RHOSP 17.1 packet flow.

And reading documentation 
https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.1/html/configuring_red_hat_openstack_platform_networking/connect-instance_rhosp-network#how-does-flat-packet-flow-work_connect-instance

On there documentation on is saying that there are bridge devices. But there are no bridge devices on RHOSP 17.1 in reality.

For example this command.

This command

ip -br link show type bridge

gives me 0 output so,

so 0 linux bridges.Then this guide is 
wrong.

https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.0/html-single/networking_guide/index#how-does-vlan-packet-flow-work_connect-instance

Or my configuration is wrong.

and also the are telling to execute brctl show, but brctl is legaxy command its not exiting on newer RHEL distros.

 # brctl show

And its deffinetly not recomended do install leagcy network packages to openstack nodes.

So i do no understand what is this documentsion.
