Configuring an SoO Set

Procedure

• Configure an SoO set using the paragraph editing mode.
  1. Run the edit xpl extcommunity-list soo soo-list-name command to enter the SoO set paragraph editing interface view.
  2. Press i to enter the text editing mode.
     

     Sets or route-filters can be configured only in the text editing mode. If you exit from the text editing mode, you can perform shortcut key operations only.

  3. Configure a start clause using the xpl extcommunity-list soo soo-list-name command in the SoO set paragraph editing interface view for an SoO set.
  4. Configure elements (SoOs of VPN routes) for the SoO set in the SoO set paragraph editing interface view and separate every two neighboring elements with a comma (,). The elements can be configured in any of the following formats:
     • 2-byte AS number:4-byte user-defined number, for example, 1:3. The AS number is an integer ranging from 0 to 65535, and the user-defined number is an integer ranging from 0 to 4294967295. The AS number and user-defined number must not be both 0s. Specifically, the SoO must not be 0:0.
     • IPv4 address:2-byte user-defined number, for example, 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number is an integer ranging from 0 to 65535.
     • 4-byte AS number in integer format:2-byte user-defined number, for example, 0:3 or 65537:3. The 4-byte AS number in integer format ranges from 65536 to 4294967295, and the user-defined number is an integer ranging from 0 to 65535.
     • 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. Generally, a 4-byte AS number in dotted notation is in the format of x.y, where x and y are both integers ranging from 0 to 65535. A user-defined number is an integer ranging from 0 to 65535. The AS number and user-defined number must not be both 0s. Specifically, the SoO must not be 0.0:0.
     • regular regular-expression: matches the VPN routes with an SoO that matches the specified regular-expression.
       

       Regular expression matching is intensive processing of CPU computing. When a large number of regular expressions are configured in an XPL policy to match a BGP route attribute and the length of the route attribute is long, the processing performance of the XPL policy deteriorates. To improve the processing performance of the routing policy, decrease the number of regular expressions or use a non-regular expression matching command.

       It is recommended that a maximum of 100 regular expressions be configured for each policy.

  5. Configure an end clause using the end-list command in the SoO set paragraph editing interface view for the SoO set.
  6. Press Esc to exit from the text editing mode.
  7. Press :wq and Enter to save the configurations and exit from the global variable set paragraph editing interface view.
     

     A message is displayed for you to confirm whether to commit the configurations when you attempt to exit from the global variable set paragraph editing interface view. To commit the configurations, press Y.

     To exit from the global variable set paragraph editing interface view without saving the configurations, press :q! and Enter.

• Configure an SoO set using the line editing mode.
  1. Run the system-view command to enter the system view.
  2. Run the xpl extcommunity-list soo soo-list-name command to enter the SoO set view.
  3. Configure elements (SoOs of VPN routes) for the SoO set and separate every two neighboring elements with a comma (,). The elements can be configured in any of the following formats:
     • 2-byte AS number:4-byte user-defined number, for example, 1:3. The AS number is an integer ranging from 0 to 65535, and the user-defined number is an integer ranging from 0 to 4294967295. The AS number and user-defined number must not be both 0s. Specifically, the SoO must not be 0:0.
     • IPv4 address:2-byte user-defined number, for example, 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number is an integer ranging from 0 to 65535.
     • 4-byte AS number in integer format:2-byte user-defined number, for example, 0:3 or 65537:3. The 4-byte AS number in integer format ranges from 65536 to 4294967295, and the user-defined number is an integer ranging from 0 to 65535.

  4. Run the end-list command to conclude the configuration of the SoO set, exit the SoO set view, and return to the system view.
  5. Run the commit command to commit the configuration.
