INE R&S ATC034 - Static Routing Examples

Default Routing

• To a next-hop
– Use the layer 2 address of the next hop for all layer 3 destinations

• To an multipoint interface
– All destinations require layer 3 to layer 2 resolution
– Layer 2 mapping table size problems
• To a point-to-point interface
– No layer 3 to layer 2 resolution required

ip route 0.0.0.0 0.0.0.0 fastethernet0/0
  需要fa0/0有啟動路由及Proxy ARP功能的設備代回ARP, 才有機會網路能通

ip route 0.0.0.0 0.0.0.0 serial0/0/0
  若此介面為NBMA(Frame-Relay)需要設定frame-relay map ip x.x.x.x 501, 才有機會網路能通
  show frame-relay map

ip route 0.0.0.0 0.0.0.0 serial0/0/0
  若此介面為point-to-point, OK.........
