First, Raleigh changed its two PVC encapsulation types in the encapsulation command using the ietf keyword. However, Mayberry cannot change its encapsulation type in the same way because only one of the two VCs terminated by Maybeny requires IETF encapsulation, while the other requires Cisco encapsulation. Mayberry was thus forced to write the command frame-relaymap using the ietf keyword, which points to the DLCI of the VC to Raleigh. using this command, the user is able to change the encapsulation settings for each VC, which changes the encapsulation type of all VCs relative to the Raleigh configuration.The second major change is the LMI configuration. The Mayberry's LMI configuration status is unchanged because the LMI uses the default auto-awareness to recognize that the LMI type is ANSI; however, due to the use of the frame-relay Imi-type ansi interface subcommand, the Mayberry must use ANSI because this command not only sets the LMI type, but also disables auto-negotiation of the LMI type.291 Chapter 14 Implementing Frame Relay Tip: LMI settings are set per physical interface, even when using subinterfaces, so the frame-relay Imi-type command is always a subcommand under the physical interface. MountPilot's VC for its arrival at Raleigh,requires the game-relaymap command to be configured using the ietf keyword, similar to the Mayberry. This change is not shown in the example here.4,Frame Relay Address MappingFigure 14-1 does not even list the DLCI for the VC. as the configuration operation described earlier, frankly, this network would work even if the user had no idea what a DLCI was! However, for exams and real-world network work, administrators need to understand how DLCI values and Frame Relay mappings are handled.Frame Relay mapping is used to send a frame to the correct DLCI of that next-hop device to match the next-hop IP address of the Frame Relay network, whose destination is the same as the LANsubnet 199.1.10.0/24
