Description: after marking each network node with IP, if you let the two nodes separated by multiple network nodes communicate, you need a "middleman" to pull strings, and you have to tell a node data step by step, and how to go to the opposite node step by step.

Static routing: manually configure static routing information so that packets with matching destination addresses can be forwarded using a dedicated line interface or next-hop IP address according to the routing information.

Advantages: simple configuration and less system resources

Disadvantages: large-scale network configuration is cumbersome and lack of flexibility, when the network topology changes, the routing information needs to be adjusted manually.

Dynamic routing: sharing and dynamically learning routing information using algorithms and protocols

Advantages: real-time, flexibility, accuracy

Disadvantages: high resource consumption and high maintenance cost

RIP and IGRP-- classful routing: routing information is published and transmitted without subnet mask

RIPv2,ospf,EIGRP,is-is,BGP---- classless routing: supports VLSM and CIDR: routing information is issued and transmitted with subnet mask marking.

OSPF,ISIS-using Dijkstra algorithm, link-state protocol

RIP,RIPv2,IGRP-uses the Bellman-ford algorithm. Distance vector protocol

EIGRP--CISCO dedicated diffusion update algorithm, which is a distance vector route like IGRP, but EIGRP supports classless routing and fast convergence
