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 DXi to an IP address in another subnet by
means of a destination gateway. Responses from the destination are
routed back to the DXi using the gateway specified for the interface in
the
IP Address Table
section.
In addition, when configuring segmented network interfaces, if the
source DXi replication, data, and management interfaces are on the
same subnet, you must add a host route on the source DXi to make sure
the replication interface is correctly selected when replicating data to
the target DXi.
See the following examples for details:
•
Example 1: Segments and Target on Different Subnets
•
Example 2: Segments and Target on the Same Subnet
•
Example 3: Segments on the Same Subnet and Target on a Different
Example 1: Segments and Target on Different Subnets
), the DXi has two segmented
interfaces, one for management traffic and one for data traffic:
• 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).
• 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.
• Using the data interface, the DXi 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 DXi 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.
