Configuring an SoO Set

Configuring an SoO Set

Site of origin (SoO) sets are used to match the SoOs of VPN routes.

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.

      NOTE:

      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 extcommunity-list soo soo-list-name) for an SoO set.
    4. Configure elements 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 IPv4 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.
      • Integral 4-byte AS number:2-byte user-defined number, for example, 0:3 or 65537:3. The integral 4-byte AS number 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 (x.y):2-byte user-defined number, for example, 0.0:3 or 0.1:0. The x, y, and user-defined number are integers 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.
        NOTE:

        In the preceding elements, either value around a colon (:) can be replaced by an asterisk (*) to match any value.

      • regular regular-expression: matches VPN routes with SoO in the specified regular expression. For detailed description about regular expressions, see NE40E Configuration Guide – Basic Configuration.

    5. Configure an end clause (end-list) 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.

      NOTE:

      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 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 IPv4 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.
      • Integral 4-byte AS number:2-byte user-defined number, for example, 0:3 or 65537:3. The integral 4-byte AS number 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 (x.y):2-byte user-defined number, for example, 0.0:3 or 0.1:0. The x, y, and user-defined number are integers 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.
        NOTE:

        In the preceding elements, either value around a colon (:) can be replaced by an asterisk (*) to match any value.

      • regular regular-expression: matches VPN routes with SoO in the specified regular expression. For detailed description about regular expressions, see NE40E Configuration Guide – Basic Configuration.

    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.

Example

NOTE:

If only paragraph editing is used as an example, the corresponding line editing is similar. To use the line editing mode, perform the operations described in paragraph editing.

For detailed set and route-filter configuration steps, see Configuration Procedures of Sets and Route-Filters Using the Paragraph Editing Mode. For detailed description about XPL clauses, see XPL Paragraph Editing Clauses.

Objective Configure an SoO set to match the VPN routes carrying the SoO (100:1, 200:1, or 300:1).
Configuration Example
<HUAWEI> edit xpl extcommunity-list soo soo-list1

xpl extcommunity-list soo soo-list1
100:1,
200:1,
300:1
end-list

The SoO set contains three elements and can match VPN routes carrying SoO 100:1, 200:1, or 300:1.

Objective Configure a route-filter to overwrite the SoOs of the VPN routes carrying at least one of the SoOs specified in the set named soo-list1 with 100:1 and 200:1.
Reference Example
<HUAWEI> edit xpl route-filter r1

xpl route-filter r1
if extcommunity soo matches-any soo-list1 then
apply extcommunity soo { 100:1,200:1 } overwrite
endif
end-filter

The route-filter references the set named soo-list1 and overwrites the SoOs of the VPN routes carrying at least one of the SoOs specified in the set with 100:1 and 200:1.
