The value of vRtrInetAggrASSet specifies whether the
aggregate route has AS-SET.
When vRtrInetAggrASSet has value of 'true(1)', the AS-Path
of the resulting aggregate will contain an AS-SET
containing all AS numbers from the contributing routes.
When vRtrInetAggrASSet has value of 'false(2)', the AS-Path
will contain no AS-SET and will be originated by the ESR.
