INE R&S ATC024 - Frame Relay Configuration Part 1

int s0/0
  encapsulation frame-relay

Port / Line Protocol
UP / UP is OK
UP/ DOWN is LMI Problem
DOWN/ DOWN is PHY Problem

show frame-relay lmi
      check Num Status Eng. Sent
      check Num Status msgs Rcvd.
      Num status Timeouts

show frame-relay pvc
show frame-relay pvc | include DLCI

debug frame-relay packet
debug frame-relay enents ------------>顯示Invers ARP的資訊

show frame-relay map

於R2上Ping 12.0.0.2會Ping不到自己............
show frame-relay map......12.0.0.1 dynamic map.....表示是透過Invers ARP學習而來
會發現沒有12.0.0.2

我們可以設定frame-relay map ip 12.0.0.2 201這樣設定靜態的ARP, 這樣就可以Ping OK...
但要注意...
frame-relay map建議...要的話全部動態學習......要的話全部靜態設定.......
因為平台不同...很可能shutdown Port後...再no shutdown起來後...dynamic map就無法學習到
Brain再次建議.........要的話全部動態學習......要的話全部靜態設定.......
