Static route function¶
[Update: May 23, 2019]
The static route function is used to add an IP address block and set an arbitrary server under the router + switch as the next hop. Using this function makes it possible to add IP addresses which can be used at the customer side in addition to the one IP address block (/24 to /28) assigned at the time of creating the router + switch.
When using the static route function, a maximum of 20 IP address blocks can be added to one router + switch.
As for the IP addresses added by static route, all IP addresses are available for the user. However, when routing on the server, there are cases in which the number of IP addresses that can be assigned to a server is less than the number of added IP addresses depending on the network configuration. For example, when one IP address is used for the network address and one IP address is used for the broadcast address.
Procedures for using the static route function are listed below.
Before adding a static route, you must first create a server for use as the next hop.
Select [Switch] in the menu on the left of the control panel. The list of created switches will appear. Double-click on the switch for which you want to set a static route.
Click [IP Address] from the tabs at the top of the screen to display a list of IP addresses assigned to the selected router + switch. If you want to use the static route function to add an assigned IP address block, click the [Add Static Route] button at the bottom right of the screen.
A screen is displayed for selecting the prefix and next hop of the IP address block which you want to add. Select a prefix from the three levels of 28 (16 IP addresses), /27 (32 IP addresses), and /26 (64 IP addresses). Select a next hop from the IP address affiliated at the time of creating the router + switch. Then, click the [Add] button.
When you finish adding the IP address block, it is shown in the pop-up menu for selecting an IP address block displayed at the top of the selection screen for the [IP address] tab.
When you select the added IP address block, the following items are displayed in the list: 1) the IP address specified for the next hop during settings to add the block, and 2) the IP address affiliated at the time of creating the router + switch. You can configure Reverse lookup settings by clicking on the pencil icon on the right-hand side.
A [Change Next Hop] button is displayed at the bottom-right of the screen listing IP address blocks which were added via the static route function.
Click the [Change Next Hop] button to display the next hop setting screen. Select the IP address which you want to change from the pop-up menu in the [Next Hop: After Change] section, and then click the [Change] button to change the next hop.
Click the [Delete] button displayed at the bottom-right of the screen listing the IP address block which you want to delete.
Once an IP address block has been deleted, the same IP address block cannot be assigned again. Please be careful when deleting IP address blocks.
