      config terminal
      no cdp run
      no ip domain-lookup
      line console 0
      no exec-t
      logg syn
      enable secret cisco
      line vty 0 4
      password cisco
      login
      host frame-relay
      frame-relay switch
      int s0/0
      encapsulation frame-relay
      frame-relay lmi-type ansi
      frame-relay intf-type dce
      clock rate 64000
      frame-relay route 104 interface s0/1 401
      frame-relay route 103 interface s0/2 301
