Topology Matching (eHRPD only)
You may specify which P-GW you wish an HSGW interface to connect with by enabling topology matching within the
FQDNs for both the HSGW service and P-GW service. Topology matching selects geographically closer nodes and
reduces backhaul traffic for a specified interface.
FQDNs for both the HSGW service and P-GW service. Topology matching selects geographically closer nodes and
reduces backhaul traffic for a specified interface.
The following optional keywords enable or disable topology matching when added to the beginning of an FQDN:
topon.interface_name
.
Beginning an FQDN with
topon
initiates topology matching with available HSGWs in the network. Once this
feature is enabled, the rest of the FQDN is processed from right to left until a matching regional designator is
found on a corresponding HSGW FQDN.

topoff.interface_name

By default, topology matching is disabled. If you enable topology matching for any interfaces within a node,
however, all interfaces not using this feature should be designated with

Example
The following command configures the FQDN for this P-GW service as
123abc.all.com
with a realm
name of
all.com
:
fqdn host 123abc.all.com realm all.com
The following command configures this P-GW service with an FQDN that enables topology matching:
fqdn host topon.interface_name.pgw01.bos.ma.node.epc
.mnc<value>.mcc<value>.3gppnetwork.org realm
node.epc.mnc.mcc.3gppnetwork.org
.mnc<value>.mcc<value>.3gppnetwork.org realm
node.epc.mnc.mcc.3gppnetwork.org
Important:
The associated HSGW service must have a corresponding FQDN similar to the following:
topon.interface_name.hsgw01.bos.ma.node.epc.mncvalue.mccvalue.3gppnetwork
.org
.org
