The value of the object tBgpPrngPlcyASOverride specifies whether
or not the customer AS number in the ASPATH attrubute is overriden
with the own AS number.
When the value of tBgpPrngPlcyASOverride is 'true', the service
provider BGP will override the customer AS number in the ASPATH
with its own AS number. Without this feature there could be
scenarios where multiple CE locations belonging to the same AS
will not be able to communicate due to a potential loop detection.
