Add Persistence Route on Local Zone.

I am trying to add the persistence route on the local zone but it shows me insufficient privileges, would it allow me to add the persistence route on the local zone or add the route via global ? 

bash-3.00# route -p add -net --.--.--.--/24 --.--.--.--

add net --.--.--.--/24: gateway --.--.--.--: insufficient privileges
