Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
■ IPv6: 0 to 128
'Ethernet Output
Device'
device-name
[StaticRouteTable_
DeviceName]
Associates an IP network interface through which the static route's
Gateway is reached. The association is done by assigning the
parameter the same Ethernet Device that is assigned to the IP network
interface in the IP Interfaces table ('Ethernet Device' parameter). To
configure IP network interface, see Configuring IP Network Interfaces.
To configure Ethernet Devices, see Configuring Underlying Ethernet
Devices.
'Gateway'
gateway
[StaticRouteTable_
Gateway]
Defines the IP address of the Gateway (next hop) used for traffic
destined to the subnet/host defined in the 'Destination' / 'Prefix Length'
field.
Note:
■ 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 'Ethernet Output Device' parameter - see above).
■ The IP network interface associated with the static route must be of
the same IP address family (IPv4 or IPv6).
Configuration Example of Static IP Routes
An example of the use for static routes is shown in the figure below. In the example, 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 Routes table must be associated with the IP network interface in
the IP Interfaces table. This is done by configuring the 'Ethernet Output Device' field in the
Static Routes table to the same value as configured in the 'Ethernet Device' field in the IP
Interfaces table.
■ The static route's Gateway address in the Static Routes table is in the same subnet as the IP
address of the IP network interface in the IP Interfaces table.
