So does Nokia SROS:

[no] static-route {ip-prefix/prefix-length | ip-prefix netmask } 
[validate-next-hop]

validate-next-hop:

This configuration option tracks the state of the next-hop in the IPv4 
ARP cache or IPv6 Neighbor Cache. When the next-hop is not reachable and 
is removed from the ARP or Neighbor Cache, the next-hop will no longer 
be considered valid. When the next-hop is again reachable and present in 
the ARP/Neighbor Cache, the static route will be considered valid.
Note: This feature is supported for directly connected next-hops only, 
and is exclusive with indirect routes.
