The sour-addr sour-wildcard argument combination matches the destination address of a route without
matching the mask in the route.
The dest-addr dest-wildcard argument combination matches the subnet mask of the route without
matching the destination address in the route. The dest-wildcard must be contiguous. Otherwise, the ACL
rule does not take effect.
