Hi, For ironic flat provider network, I found it's hard to scale manually (for many racks). So I'm trying to use routed network for the purpose. One blur thing for routed network is how we can handle segment connectivity. >From reference (https://docs.openstack.org/neutron/latest/admin/config-routed-networks.html), there is future work about dynamic routing protocol though, I could not find any hints for the functionality. How do you guys using routed network handle the segments' connectivity? Is there any project to speak subnet info via BGP? Thanks in advance.
