[Network] 网络链路层路由算法总结

Routing protocols

• Routing information protocols（RIP）
  • Algorithm: Distance Vector
  • 
• Open Shortest Path First (OSPF)
  • Algorithm: Link State
  • 
• BorderGatewayProtocol (BGP)
  • Another type of vector Routing: widely used in the AS Protocals
  • demo
    
  • Problem with integrate wit intra domain Routing
    • static method ALL unknown IPs send to D.
    • Entry Translation: high cost
    • interior BGP

ARP

之前打ctf 的时候搞过这个协议，主要是在MAC 层能对网卡欺骗，从而把destination 当成自己，就能抓取同路由器下的其他设备的包。

这种需要规避就得ip-mac 绑定。
