The functionality provided by this command can also be used to restrict access to particular APNs. To restrict
access based on a particular criteria (domain name, mcc/mnc, etc.), the “virtual” APN reference should refer
to an APN that is not configured on the system and contains the desired rule. All calls matching the
configured rule would then be denied with a reason code of 219 (DBH), Missing or Unknown APN.
eWAG
For eWAG, in this release only the
access based on a particular criteria (domain name, mcc/mnc, etc.), the “virtual” APN reference should refer
to an APN that is not configured on the system and contains the desired rule. All calls matching the
configured rule would then be denied with a reason code of 219 (DBH), Missing or Unknown APN.
eWAG
For eWAG, in this release only the
access-gw-address
Virtual APN configuration option is supported.
For information on how virtual APN configuration can be used in eWAG deployments, refer to the Enhanced
Wireless Access Gateway Administration Guide.
IPSG
For IPSG, in this release only the following Virtual APN configuration options are supported:
Wireless Access Gateway Administration Guide.
IPSG
For IPSG, in this release only the following Virtual APN configuration options are supported:
access-gw-address
(RADIUS client in the case of IPSG)
msisdn-range from msisdn_start_range to msisdn_to_range
rat-type
All these attributes are sent in access-request in Auth-Proxy mode or Acct-Start in other modes to trigger
Virtual APN selection.

P-GW/SAEGW
The Virtual APN feature allows a carrier to use a single APN to configure differentiated services. The APN
that is supplied by the MME is evaluated by the P-GW in conjunction with multiple configurable parameters.
Then, the P-GW selects an APN configuration based on the supplied APN and those configurable parameters.
APN configuration dictates all aspects of a session at the P-GW. Different policies imply different APNs.
After basic APN selection, however, internal re-selection can occur based on the following parameters:

In StarOS v12.x and earlier, the P-GW supports a maximum of 1024 Virtual APNs in a system. In StarOS
v14.0 and later, the P-GW supports a maximum of 2048 Virtual APNs in a system.

Example
The following commands configure two “virtual” APNs, priority 1 references the bigco APN with a domain
rule of bigco.com, priority 2 references the bigtown APN with a mobile country code rule of
rule of bigco.com, priority 2 references the bigtown APN with a mobile country code rule of

and a
mobile network code rule of
