If no other problems are found on R2 besides the inactive PVC, then there may be a problem with the Frame Relay provider's network, so the next step is to call the service provider. But other problems may also be found on the remote router. For example, the access link to R2 is shut down in this subsection in order to create a failure condition and to demonstrate the show command, so following troubleshooting step 1 on R2 enables you to quickly check and identify this problem. However, if further troubleshooting shows that the PVCs on both routers are inactive, the root cause of this problem lies in the Frame Relay provider's network.Identifying the root cause associated with a PVC is relatively easy in the deleted state. A deleted state means that the configuration of the Frame Relay switch does not match the configuration of the router, that is, the DLCI configured on the router is not yet configured on the switch. It is possible that the provider says that the PVC is configured using a specific DLCI but it is not, or it is possible that the administrator of the router has configured the wrong DLCI value. (5) Subinterface status.Subinterfaces have line status and protocol status codes just like physical interfaces. However, because the subinterface is virtual, the status codes and their meaning are somewhat different from the physical interface. This section briefly describes how Frame Relay subinterfaces work and how the IOS determines that a Frame Relay subinterface should be in308 Chapter 14 Implementing Frame Relay up/up State or in the down/down state. Frame Relay configuration can associate one or more DLCIs with a subinterface using two commands: frame-relay interface-dlci and frame-relay map0 All DLCIs associated to a particular subinterface, IOS determines the subinterface state using the following rules. ......... .down/down:All DLCI's associated to this sub-interface are inactive or deleted, or are the underlying physical interface (2^ is in the ,not up/up state.' ,.up/up:At least one DLCI associated to this interface is in an active or static state. For example, to bow I send the problem shown in Example 14-22, simply shut down the Frame Relay access links to R2 and R3. Figure 14-9 shows the next LMI status message that switch S1 sends to R1.S0/0/0.2 Point-to-Point DLCI 102
