INE R&S ATC026 - Frame Relay Switching

Frame Relay Switching

• Enable Frame Relay Switching
– frame-relay switching

• DCE end oflink provides clocking
– clock rate [rate]
– show controllers serial

• Frame Relay Switch is logical DCE
– frame-relay intf-type dce

• Legacy syntax on both links
– frame-relay route [in-DLCI] interface [int] [out-DLCI]

• New syntax globally
– connect [name] [interface-1] [DLCI-1] [interface-2] [DLCI-2]

======================================================

以R3為範例

frame-relay switching

int s1/2
  encapsulation frame-relay
  frame-relay intf-type dce
  clock rate 64000
  frame-relay route 100 interface serial 1/3  ---> 可以被connect用一行取代

int s1/3
  encapsulation frame-relay
  frame-relay intf-type dce
  clock rate 64000
  frame-relay route 200 interface serial 1/2  ---> 可以被connect用一行取代

connect R1_TO_R2 serial 1/2 100 serial 1/3 200  ---> 用一行connect取代兩行route
