Differences between rip and OSPF and configuration commands

RIP：Routing Information Protocol（ Routing information protocol ）

• RIP It's based on Distance vector Routing protocol of the algorithm
• Slow convergence , Suitable for small and medium-sized networks
• be based on UDP transmission , Port number 520
• Most support 15 jump ,16 Jumping means unreachable

The number of hops of the directly connected network defaults to 0

OSPF：Open Shortest Path First( Open shortest path first )

• OSPF Is based on Link state Algorithm and Internal gateway Protocol routing protocol
• OSPF Only propagate the routing information that the peer device does not have , Convergence is rapid
• OSPF Work directly on IP Layer above ,IP The agreement number is 89
• Send the protocol packet with multicast address

Link state ： Describe the router interface and its neighbor router relationship , All link state information constitutes the link state database

Roueter ID: Uniquely identify one that allows OSPF The router , Each run OSPF All routers have one Router ID

OSPF and RIP V2 All support VLSM
