| Hi guys, I just noticed if you have multiple floating ip pools, (different subnet) with nova-network - the floating ips don't work if the second pool doesn't have any route available on the compute node (using openstack multi_host but I guess that apply even if you don't use it) for example floating-ip range :10.0.10.0/27 -> same IP range of the compute node (that has routing rules for that) : works floating-ip range: 46.46.46.0/27 -> other subnet the compute node doesn't have any route for : doesn't work Because basically, doesn't that mean we are trying to assign two WAN routing to the same computer? if so I think it's about setting up priorities on two new routing tables: ip rule add prio 201 from IP1/NETMASK1 table 201 ip rule add prio 202 from IP2/NETMASK2 table 202 ip route add default via GATEWAY1 dev eth0 src IP1 proto static table 201 ip route append prohibit default table 201 metric 1 proto static ip route add default via GATEWAY2 dev eth0 src IP2 proto static table 202 ip route append prohibit default table 202 metric 1 proto static ip rule add prio 221 table 221 ip route add default table 221 proto static nexthop via GATEWAY1 dev eth0 weight 2 nexthop via GATEWAY2 dev eth0 weight 3 How does nova-network manages the multiple pools with IP that are routed to the same nodes, even if that last doesn't have any ip within these pools? thank you! |
