Management Control Using a Dedicated DLCI
Management control through a dedicated DLCI is typically used by service
providers to provide a single point of access (i.e., a standard, nonmultiplexed
DLCI), usually to the customer’s central site unit, to manage the customer’s
network. See
Service Provider Management Overview on page 2-3 for a typical
service provider configuration.
Nonmultiplexed DLCIs must be used when in-band management communication
is desired between any non-FrameSaver unit and a FrameSaver unit.

Data
As shown in the example, in-band management is accomplished through the
dedicated PVC between the two units. Management data for non-FrameSaver
Unit B goes to FrameSaver Unit A first, which then routes it into the dedicated
PVC between the two units. Only management data is carried over the PVC –
source DLCI 60 to destination DLCI 20.
If using this method to access remote sites, map or subinterface statements must
be added to the router at the central site to ensure that management traffic
destined for the remote site units is routed to the FrameSaver unit at the central
site by the router. Once traffic gets to the central site FrameSaver unit, it is
rerouted to the appropriate remote site FrameSaver units.
NOTE:
The router to be used for management must configure a local PVC between
the router and the FrameSaver unit to support RFC 1490 or Cisco
encapsulation. Typically, this is done using a map or subinterface statement
on the router. If the FrameSaver unit is located with the NMS at the central
site and in-band management through the frame relay network is desired to
manage remote site units, map statements must also be added to the router
for the remote units.
Depending upon the router, a single subinterface statement using a subnet
may be used instead of multiple map statements. The subinterface method
assumes that all the FrameSaver units are on a different subnet than the
endpoint routers.

Chapter 8, Configuration Options, for additional Inverse ARP and Standard RIP
information.
