What is 10.0.0.0/24 network for and 172.24.4.2/24 network for ? I guess you
are using Neutron. That makes network complicated. I think you can try to
debug Neutron.
And why are you using two routes to the same network?:

*172.24.4.0        162.242.233.1      255.255.255.0       UG     0
0        0 eth0172.24.4.0        0.0.0.0                255.255.255.0
  U      0      0        0 br-ex*
