what is the correct routing table of openstack controller? -

-

i can't seem figure out should routing table of openstack controller 2 interfaces same network, tried several configurations, 1 working disable 1 interface, that's not want do

destination     gateway         genmask         flags metric ref    use iface 0.0.0.0         10.0.4.2        0.0.0.0         ug    0      0        0 eth2 10.0.0.0        0.0.0.0         255.255.255.0   u     0      0        0 eth0 10.0.4.0        0.0.0.0         255.255.255.0   u     0      0        0 eth2

ignore 10.0.4.2 used internet connectivity. following entry needed openstack work. routing openstack management network. assume controller ip 10.0.0.11 . 

10.0.0.0        0.0.0.0         255.255.255.0   u     0      0        0 eth0
