104 Chapter 5 Configuring the XStack Storage
5.3.9 Adding, Viewing, and Deleting IP Route Tables
Routing is the process of deciding the disposition of each incoming and outbound packet that the
XStack Storage handles. Using the XStack Storage management console, you can view the XStack
Storage’s routing table.
If a route being used encounters problems, you can use the XStack Storage management console
to add route tables. Adding a route is also useful if you discover a quick alternative route to the
destination. You can also use the XStack Storage management console to delete routes.
To add, view, and delete IP route tables, use the following procedure.
1. On the View menu, click View Manual Route. The View Route Table appears, with the
current route tables shown (see
Figure 5-41).
Figure 5-41. View Route Table
2. To add a route to the routing table, click the Add button. Then, when the dialog box in
Figure 5-42 appears, complete the fields and click OK. As you add route entries, record the
information in
Table D-6 on page 172.
– Destination. Enter the IP address of the destination for this route.
– Netmask. Enter the netmask (also known as a subnet mask) associated with the network
destination or press the Tab key to automatically set the default subnet mask to
255.255.255.0. Because of the relationship between the destination and the subnet
mask in defining routes, the destination cannot be more specific than its corresponding
subnet mask. In other words, there cannot be a bit set to 1 in the destination if the
corresponding bit in the subnet mask is a 0.
– Gateway. Specifies the forwarding or next hop IP address over which the set of addresses
defined by the network destination and subnet mask are reachable. For locally attached
subnet routes, the gateway address is the IP address assigned to the interface that is
attached to the subnet. For remote routes, available across one or more routers, the
gateway address is a directly reachable IP address that is assigned to a neighboring
router.
