一些较常见的IP协议号
协议号
1 Internet Control Message Protocol (ICMP)
2 Internet Group Management Protocol (IGMP)
3 Gateway to Gateway Protocol (GGP)
4 IP in IP
6 Transmission Control Protocol (TCP)
8 Exterior Gateway Protocol (EGP)
17 User Datagram Protocol (UDP)
35 Inter-Domain Policy Routing Protocol (IDPR)
45 Inter-Domain Routing Protocol (IDRP)
46 Resource Reservation Protocol (RSVP)
47 Generic Routing Encapsulation (GRE)
54 NBMA Next Hop Resolution Protocol (NHRP)
88 Cisco Internet Gateway Routing Protocol (IGRP)
89 Open Shortest Path First (OSPF)

88 Cisco Internet Gateway Routing Protocol (IGRP)
89 Open Shortest Path First (OSPF)
因为OSPF数据承载于IP数据包内,故为OSPF 网络层 协议号89
BGP 传输层 协议号179
IGRP 传输层 协议号9
EIGRP 传输层 协议号88
RIP 应用层 协议号520
TCP 网络层 协议号6
UDP 网络层 协议号17
