[ops] how to setup bgp-to-the-host and Neutron Dynamic Routing ?

Hi,

In my setup, the bgp-to-the-host part is already operational. We're using IPv6 local link to 2 switches on each host, each of them advertising for itself to both routers. Now, I'm trying to add Neutron stuff to it.

In my setup, I don't have any IPv4 on my nics, both have ipv6 local link only. So, where do I connect br-ex? I don't have a bond0 interface to connect to anymore...

Then, we do have an FRR instance to do the bgp-to-the-host IPv4 routing on each host. How does this work on the hosts where the dr-agent is running? Can it re-use the FRR that I've setup to do the route advertisements too? Or do I need another instance of a routing daemon?

Cheers,
