ccna 101.After the planning is complete, the configuration is performed step-by-step according to the choices made when planning the network. The following list summarizes the configuration steps, and it serves primarily as a learning tool. (There is no need to memorize the steps here; it is simply a tool to assist in organizing thought about configuration.). Step I Configure the physical interface to use frame relay encapsulation (encapsulationframe-relay interface subcommand). Configure a Step 2 IP address on the interface or subinterface (ipaddress subcommand). Step 3 (Optional) Manually set the LMI type at each physical serial interface (frame-relay Imi-type interface subcommand). Step 4 (Optional) Change the default encapsulation type cisco to ietf by doing the following.a,For all VCs on the interface, add the ietf keyword to the encapsulationframe-relay interface subcommand.b.For an individual VC, add the ietf keyword to the frame-relay interface dlci interface subcommand (for point-to-point subinterfaces only) or the framerelay map command. Step 5 (Optional) If reverse ARP is not used (by default) to map the DLCI to the IP address of the next-hop router, use the frame-relaymapipdlciip-addressbroadcast subinterface subcommand to determine the static mapping. Step 6 On the subinterface, associate a DLCI (point-to-point) or multiple (multipoint) DLCIs with the subinterface using one of the following two methodsa.Use the frame-relayinterface-dlcidlci subinterface command.b.Use the frame-relay mapipdlciip-addressbroadcast subinterface subcommand to have an effect on static mapping. This subsection next shows an example for all of the above configuration steps and discusses how to verify that the Frame Relay network is functioning properly.2. Configuring with a Physical Interface and an IP SubnetThe first example shows what is probably the shortest Frame Relay configuration that uses only the first two of the configuration steps above. the design solution for the first example includes the following options.Install an access link between the 3 routers.
