Message Description

    Add [host | network] %s: gateway %s options %x
            The specified route is being added to the tables. If
            the gateway address used was not the primary address of
            the gateway (the first one returned by gethostbyname),
            the gateway address is printed numerically as well as
            symbolically.

    Bitmask cannot be used with change command
            The optional /bitmask parameter was specified with the
            change command. Do not specify a bit mask with the change
            command.

    Change [ host | network ] %s: gateway %s oldgateway %s\

      oldinterface %s
            The specified route is being modified in the tables.

    Delete [ host | network ] %s: gateway %s options %x
            The specified route is being deleted from the tables. If
            the gateway address used was not the primary address of
            the gateway (the first one returned by gethostbyname),
            the gateway address is printed numerically as well as
            symbolically.

    %s %s done
            When you use the flush command, each routing table entry
            deleted is indicated with a message of this form.

    Entry exist
            An add operation was attempted for an entry that already
            exists in the routing tables.

    Gateway must be 127.0.0.1 for reject and blackhole routes.
            The gateway value is incorrect for creating reject and
            blackhole routes.

    Invalid bitmask
            The bitmask specified is not in the range of 1 to 32,
            inclusive.

    Netmask cannot be used with bitmask.
            The -netmask modifier was specified together with a CIDR
            bit mask.

    Netmask cannot be used with change command
            The optional -netmask modifier was specified with the
            change command. Do not specify a network mask with the
            change command.

    Network is unreachable
            An attempt to add a route failed because the gateway
            listed was not on a directly connected network. The next
            hop gateway must be given.

    Not in table
            A delete operation was attempted for an entry that was
            not present in the tables.

    Routing table overflow
            An add operation was attempted, but the system was low on
            resources and was unable to allocate memory to create the
            new entry.
