Managing 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
- LLB policies
- 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 specific location inside the country, such as Beijing or Guangdong, rather than simply China.
ISP address book types shows the three types of address book entries:
- Predefined—Addresses and associated 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.
- 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 can be found in more than one address book, the results are returned in the following priority:
The text file for the Restored entries has the following format:
#this is a comment line
#this is a comment line too
You use the Restore utility to import the file and the Back Up utility to export it. This operation will back up the current restored ISP address books, however, it does not back up the predefined addresses or user-configured entries.
You use the Clean utility to erase entries that were imported from the text file. This operation will erase the current restored ISP address books, however, it 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.
