Figure 210: Interface Routing: Example 2
Example 3: Segments on the Same Subnet and Target on a Different Subnet
In the example below (see "Interface Routing: Example 3" on page 306), the ETERNUS
CS800 has two segmented interfaces, one for data and management traffic, and one for
replication traffic:
l The source ETERNUS CS800 management/data IP address and the source ETERNUS
CS800 replication IP address are on the same subnet (192.168.10.x). The target
ETERNUS CS800 IP address is on a different subnet (192.168.20.x)
l To make sure the replication segment is used when communicating with the target
ETERNUS CS800, you must add a network route in the Routing Details section on the
source ETERNUS CS800.
In this example, you would specify the following routing details for the replication
interface on the source ETERNUS CS800:
Destination Use the subnet of the target ETERNUS CS800
(192.168.20.0).
Dest Netmask Use 255.255.255.0.
Dest Gateway Use the IP address of the gateway (192.168.10.1).
l In addition, to enable communication with the target ETERNUS CS800 by means of the
gateway, you must add a second host route in the Routing Details section on the
source ETERNUS CS800.
In this example, you would specify a second set of routing details for the replication
interface on the source ETERNUS CS800:
Destination Use the IP address of the gateway (192.168.10.1).
Dest Netmask Use 255.255.255.255.
Dest Gateway Use the replication IP address of the source ETERNUS
CS800 (192.168.10.100).
