Destination: The host or network to which this route offers
access should be entered here in CIDR format, where the
address is followed by a slash and then the number of bits
defining the netmask, e.g. 192.168.0.1/24 for IPV4 or
2001:db8::
/32 for IPV6.
•
Gateway: Enter the IP address of the host which serves as
the gateway to the specified destination.
•
ip route args: This field field can be used to modify the
invocation of the associated ip route add command in
order to, e.g., set the route metric. The options that can be set
here are mostly highly technical and should rarely be
required. Please see http://linux.die.net/man/8/ip for more
information.
