AudioCodes Mediant 1000B - Configuration Example of Static IP Routes

Version 7.2 151 Mediant 1000B Gateway & E-SBC
User's Manual 12. Network
Parameter Description
value of 0 to 64 for IPv6 interfaces.
Ethernet Output Name
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 on page 142. To configure Ethernet Devices,
see Configuring Underlying Ethernet Devices on page 139.
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 'Device Name' parameter - see above).
 The IP network interface associated with the static route must
be of the same IP address family (IPv4 or IPv6).
12.6.1 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
Name' field in the Static Routes table to the same value as configured in the 'Ethernet
Device' field in the IP Interfaces table.
