This table contains the list of aggregate routes
configured on this APN. Gateway uses a static host route
to forward user data packets for each PDP or Bearer context
received from Gi interface to Gn interface. Using the
aggregate route (address range), total number of static
routes implemented in the Gateway for PDP or Bearer requests
can be greatly reduced. If there is no aggregate route
configured on this access-point, then default aggregate
routes configured on Gateway will be used.
