Be sure to configure the frame relay interface on the router to use the same

management protocol as the switched network to which it is connected. For

information about configuring frame relay, see Chapter 3, “Customizing Frame

Relay.”

Frame Relay SVC Signaling and LAPF

Figure 2-5 shows the layers of protocol standards for frame relay signaling:

• The LAPF Core layer defines basic frame relay protocol for both PVCs and

SVCs and supports the reliable transfer of multiple numbered frames over

SVCs.

• The DLCMI layer defines link management protocol for PVCs.

• The LAPF and Q.933 layers define link management protocol for SVCs.
