For example,

37.187.200.10 /24 ( 255.255.255.0 )
With a default gateway of
37.187.200.254
( The default gateway is the IP of OVH's next hop layer3 device - So OVH should know this for you )
The static IP ( the /32 one )
Has:
IPADDR=37.187.235.XXX
NETMASK=255.255.255.255
NO GATEWAY
Essentially, your server will use the normal default gateway for data sent to the /32 ( 255.255.255.255 ) IP Address.
On OVH's core network, They will have a route pointing your failover / backup IP to your current one.
I have no idea if this helps you in any way, but at least theres some info here that may guide you..
