10.9 System
Understanding Interface Routing
For a network on the interface to communicate with a host located on a different subnet,
you must specify routing information in the
Routing Details
section. Routing is used to
direct outgoing traffic from a network interface on the ETERNUS CS800 to an IP address in
another subnet by means of a destination gateway. Responses from the destination are
routed back to the ETERNUS CS800 using the gateway specified for the interface in the
IP
Address Table
section.
In addition, when configuring segmented network interfaces, if the source ETERNUS CS800
replication, data, and management interfaces are on the same subnet, you must add a
host route on the source ETERNUS CS800 to make sure the replication interface is correctly
selected when replicating data to the target ETERNUS CS800.
See the following examples for details:
"Example 1: Segments and Target on Different Subnets" on page 304
"Example 2: Segments and Target on the Same Subnet" on page 305
"Example 3: Segments on the Same Subnet and Target on a Different Subnet" on page 306
Example 1: Segments and Target on Different Subnets
In the example below (see
"Interface Routing: Example 1" on page 305
), the ETERNUS
CS800 has two segmented interfaces, one for management traffic and one for data traffic:
l
The management interface is assigned to the 10.30.24.x subnet in the
IP Address
Table
section. This subnet connects to the corporate network by mean of the default
gateway (10.30.24.1).
l
The data interface is assigned to the 10.20.20.x subnet in the
IP Address Table
section. This subnet connects to a gateway at 10.20.20.1.
l
Using the data interface, the ETERNUS CS800 needs to connect to a backup host that is
on the 10.50.50.x subnet. Because this host is not on the same subnet as the data
interface, the ETERNUS CS800 cannot communicate with the host unless you specify
routing information in the
Routing Details
section.
In this example, you would specify 10.50.50.0 for destination network, 255.255.255.0 for
the destination netmask, and 10.20.20.1 as the destination gateway.
The gateway specified in the
IP Address Table
section is for
incoming
traffic to
the interface. The gateway specified in the
Routing Details
section is for
outgoing
traffic from the interface.
