[neutron] neutron router gateway set will waste a public ip. How to avoid it?
Hi, when i set a gateway for router,(neutron router-gateway-set router external-network), it will allocate a IP address for qg interface. For me, this IP address is useless. I use floatingip to connect external network. Is there a way to avoid allocating this gateway IP for router qg interface? --
Hi, There is no such possibility AFAIK. Maybe some plugins different than ML2 will allow to do that somehow. On Wed, Jun 17, 2020 at 11:54:42AM +0800, Zhengyu Pan wrote:

Maybe this would be possible with service networks and have the peer to peer connection for the qrouter on a private /30 network and define appropriate static routes to the qrouter. On 17/6/20 6:54 π.μ., Zhengyu Pan wrote:
