Comment 2 for bug 1896537

I looked there and I saw the external network subnet is the same as subnet used for the control plane. It means there was a route for the FIP to the br-ctplane instead of br-ex, br-ex was used in the bridge mappings for the given provider network.

When I changed the bridge mappings to use br-ctplane instead, the pings works. However this is not the solution because I think the control plane subnet should differ from the external public subnet. The network configuration should be changed for the external network so this can work properly (separate external and control plane networks).
