devstack juno networking route between networks

Question

How can I configure neutron to allow routing between private networks in the same tenant? When I connect two private subnets with a router, I can't ping instances across the router.

Answer 1

The router isn't enough. You also need to specify a security group rule allowing incoming ICMP packets to the VMs.

Answer 2

听起来您需要为每个网络设置主机路由或将默认网关设置为连接两个网络的路由器。
