Figure 29. Typical Integrated Service Access Scenario with dedicated PVCs
Integrated service access
The example in
figure 29
shows a typical integrated service access scenario, where different service providers are
accessed via permanent virtual circuits (PVCs) on Frame Relay over the serial interface of a SmartNode.
The multi service provider (MSP) offers both Internet access and voice services based on IP. The virtual private
network (VPN) provider offers secure interconnections of local access networks (LAN) via its public wide area
network based on IP. Since both providers are working independently, the SmartNode needs a configuration,
which has two dedicated PVCs on Frame Relay. The first PVC, labeled as PVC 1, connects to the MSP access
device. The second PVC, labeled PVC 2, connects to the VPN provider access device on the leased line network.
A SmartNode is working as a DTE and accesses the leased line network via a leased line modem connected to
the serial interface. The hardware port protocol X.21 is used on the serial interface on slot 0 and port 0.
Devices accessing the MSP and VPN services are attached to the 100 Mbps Ethernet port 0/0 on the
SmartNode. For that reason, an IP context with three logical IP interfaces bound to Ethernet port 0/0, PVC 1
and PVC 2 on serial port 0/0 as shown in
figure 29
has to be configured for the SmartNode. The IP interfaces
are labeled to represent the function of their configuration. Hence Ethernet port 0/0 is named lan, PVC 1 is
named external since external services are accessed via this PVC, and PVC 2 is named internal to indicate the
private network interconnection via this PVC.
