    The route target extended community for VPLS auto-discovery defines the import and export
    policies that a VPLS instance uses. The export route target sets an extended community attribute
    number that is appended to all routes that are exported from the VPLS instance. The import route
    target value sets a filter that determines the routes that are accepted into the VPLS instance. Any
    route with a value in its import route target contained in its extended attributes field matching the
    value in the VPLS instance’s import route target are accepted. Otherwise the route is rejected.
