Destination
[StaticRouteTable_Destination]
Prefix Length
[StaticRouteTable_PrefixLength
]
The address of the host/network you want to reach is determined by an AND operation that is applied
to the fields 'Destination' and 'Prefix Length'. For example, to reach the network 10.8.x.x, enter
10.8.0.0 in the 'Destination' field and 16 in the 'Prefix Length'. As a result of the AND operation, the
value of the last two octets in the 'Destination' field is ignored. To reach a specific host, enter its IP
address in the 'Destination' field and 32 in the 'Prefix Length' field.

13.4.1 Configuration Example of Static IP Routes

An example of the use for static routes is shown in the figure below. In the example
scenario, the device needs to communicate with a softswitch at IP address 10.1.1.10.
However, the IP network interface from which packets destined for 10.1.1.10 is sent, is
configured to send the packets to a Default Gateway at 10.15.0.1. Therefore, the packets
do not reach the softswitch. To resolve this problem, a static route is configured to specify
the correct gateway (10.15.7.22) in order to reach the softswitch.
Note the following configuration:

The static route is configured with a subnet mask of 24 (255.255.255.0), enabling the
device to use the static route to send all packets destined for 10.1.1.x to this gateway
and therefore, to the network in which the softswitch resides.

The static route in the Static Route table is associated with the IP network interface in
the Interface table, using the 'Interface Name' fields.
Version 7.0
Assigns an IP network interface through which the static route's
Gateway is reached.
This value must be identical to the value configured for the network
interface in the 'Interface Name' parameter of the Interface table
(see Configuring IP Network Interfaces on page 145).
Defines the IP address of the destination host/network. The
destination can be a single host or a whole subnet, depending on
the prefix length configured for this routing rule.
Defines the Classless Inter-Domain Routing (CIDR)-style
representation of a dotted-decimal subnet notation of the
destination host/network. The CIDR-style representation uses a
suffix indicating the number of bits that are set in the dotted-
decimal format. For example, the value 16 represents subnet
255.255.0.0. The value must be 0 to 31 for IPv4 interfaces and a
value of 0 to 64 for IPv6 interfaces.
Defines the IP address of the Gateway (next hop) used for traffic
destined to the subnet/host defined in the 'Destination' / 'Prefix
Length' field.
Notes:

The Gateway's address must be in the same subnet as the IP
address of the network interface that is associated with the
static route (using the 'Interface Name' parameter - see above).

The IP network interface associated with the static route must
be of the same IP address family (IPv4 or IPv6).
Defines an arbitrary name to easily identify the static route rule.
The valid value is a string of up to 20 characters.
