Managing the ISP address books
ISP address books contain IP subnet addresses and associated province location settings for ISP links.
The following policies use the ISP address book objects:
• ISP routes
• LLB proximity routes
• GLB data center configuration
The province setting is used in GLB deployments in China to enable location awareness that is province-specific. For example, a user can be directed to a data center in Beijing or Guangdong rather than simply China.
Figure 51 shows the three types of address book entries:
• Predefined—Addresses and assocaited province location settings for China Mobile, China Telecom, and China Unicom. The IP subnet addresses in the predefined address books are not exposed in the user interface. The predefined package is provided to make it easier for you to configure a route when all you know and all you need to know is the name of the ISP that hosts the link.
• Restored—Addresses imported from a text file. The IP subnet addresses in the restored address books are not exposed in the user interface. “Restored” addresses can help you rapidly build an ISP address book configuration. “Restored” addresses can help you rapidly build an ISP address book configuration.
• User-defined—In the ISP address configuration, you can modify the predefined and restored address books by specifying subnets to add or exclude from them. This gives you flexibility in case you encounter address conflicts or the ISP instructs you to add a subnet address manually.
You can also create new user-defined entries for other ISPs.
Note: In systems with multiple VDOMs, these commands apply to the current VDOM only. In other words, if you configure an exclusion, it is applicable to the current VDOM only; it does not change the predefined address book.
You can use the Inquire utility to see whether an IP address belongs to any of the address books. If an address is can be found in more than one address book, the results are returned in the following priority: user-defined, restored, predefined.
The text file for the Restored entries has the following format:
#this is a comment line
ISP name:ABC
Province:Beijing
1.1.1.0/24
Province:Unknown
2.2.0.0 255.255.0.0
#this is a comment line too
3.3.3.3/32
ISP name:DEF
Province:Shanghai
4.4.4.0 255.255.255.0
5.5.0.0/16
You use the Restore utility to import the file and the Back Up utility to export it.
You use the Clean utility to erase entries that were imported from the text file. The clean operation does not affect the predefined addresses or user-configured entries. If a restored entry has user-configured elements (for example, an exclude list), the clean operation clears the addresses but preserves the configuration and converts it to a user-defined type.
Basic Steps
1. Create ISP address objects.
2. Select them when you configure your policies.
Before you begin:
• You must have Read-Write permission for System settings.
To edit or create an ISP address book object:
1. Go to System > Shared Resource > Address.
2. Click the ISP Address tab.
3. Click the Edit icon to edit an existing entry or the Add link to create a new configuration.
4. Complete the configuration as described in
Table 72.
5. Save the configuration.
Table 72: ISP address object configuration
Settings | Guidelines | | |
Name | Configuration name. Valid characters are A-Z, a-z, 0-9, _, and -. No spaces. After you initially save the configuration, you cannot edit the name. |
Address | Address/mask notation specifying a subnet to add it to the address book entry. |
Excluded Address | Address/mask notation specifying a subnet to exclude from the address book entry. Create exclusions to predefined and restored address books only. |
Province | Select the associated province location. The configuration supports the following selections: |
| • Anhui • Beijing • Chongqing • Fujian • Gansu • Guangdong • Guangxi • Guizhou • Hainan • Hebei • Heilongjiang | • Henan • Hubei • Hunan • Jiangsu • Jiangxi • Jilin Liaoning • Neimenggu • Ningxia • Qinghai • Shandong • Shanghai | • Shanxi (Taiyuan) • Shanxi (Xian) • Sichuan • Tianjin • Xianggang • Xinjiang • Xizang • Yunnan • Zhejiang • Unknown |
