Configuring an RD Set

Procedure

• Configure an RD set using the paragraph editing mode.
  1. Run the edit xpl rd-list rd-list-name command to enter the RD 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 (xpl rd-list rd-list-name) for an RD set.
  4. Configure elements (RDs of VPN routes) for the RD set in the RD 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:
     • 16-bit AS number:32-bit user-defined number, for example, 101:3. The AS number is an integer ranging from 0 to 65535, and the user-defined number is an integer ranging from 0 to 4294967295.
     • 32-bit IP address:16-bit 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, 65537:3. The AS number ranges from 65536 to 4294967295. The user-defined number ranges 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.
     • regular regular-expression: matches the VPN routes with an RD 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 RD set paragraph editing interface view for the RD 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 RD set using the line editing mode.
  1. Run the system-view command to enter the system view.
  2. Run the xpl rd-list rd-list-name command to enter the RD set view.
  3. Configure elements (RDs of VPN routes) for the RD set and separate every two neighboring elements with a comma (,). The elements can be configured in any of the following formats:
     • 16-bit AS number:32-bit user-defined number. For example, 101:3. The AS number ranges from 0 to 65535, and the user-defined number ranges from 0 to 4294967295.
     • Integral 4-byte AS number:2-byte user-defined number, for example, 0:3 or 65537:3. An AS number ranges from 0 to 4294967295. A user-defined number ranges 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. A 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that range from 1 to 65535 and from 0 to 65535, respectively. A user-defined number ranges from 0 to 65535.
     • 32-bit IP address:16-bit 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 ranges from 0 to 65535.
     • regular regular-expression: matches VPN routes with RDs in the specified regular expression.
       

       Regular expression processing is computing-intensive. 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.

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