ccna 2 chapter 8 pdf.. The router matches the route that forwards the packet to the point-to-point interface.The router looks for the (unique) frame-relayinterface-dlci configuration command on that subinterface and uses that DLCI when encapsulating that packet.Finally. the debug frame-relay Imi command output enumerates the query information for the sender and receiver LMIs. The switch sends a status message and the DTE (router) sends a status query. The Cisco IOS software is set by default to send and expect to receive these status messages. Cisco IOS software disables LMI status messages with the nokeepalive command. Unlike other interfaces, Cisco survivorship messages are not transmitted between routers via Frame Relay. Instead, they are used only to detect connectivity between that router and its local Frame Relay switch6. using multipoint interface configuration Users can also choose to use multipoint subinterfaces for Frame Relay configuration. The final network example is based on the network shown in Figure 14-6 that uses both multipoint subinterfaces and point-to-point subinterfaces. Example 14-13 through Example 14-17 show the configuration process for this network. Table 14-2 summarizes the addresses and subinterfaces used.
