characteristic
characteristic : A way of routing , Route item (routing entry) Manually configured by , Not dynamically . Unlike dynamic routing , Static routing is fixed , Will not change , Even if network conditions have changed or been reconfigured . Generally speaking , Static routing is added by the network administrator to the routing table one by one .
advantage : Another advantage of using static routing is high network security . Dynamic routing requires routers to exchange their routing tables frequently , The analysis of routing table can reveal the network topology and network address information . therefore , For the sake of network security, static routing can also be used . It doesn't take up network bandwidth , Because static routing does not generate update traffic .
shortcoming : Static routing is usually not suitable for large and complex network environments . One side , It is difficult for network administrators to fully understand the topology of the whole network ; On the other hand , When the network topology and link state change , The static routing information in the router needs to be adjusted in a wide range , This work is very difficult and complicated . When the network changes or the network fails , Cannot reroute , It's very likely that routing will fail .
Purpose
l Static routing has different purposes in different network environments :
l When the network structure is simple , Just configure the static route to make the network work normally .
l In a complex network environment , Configuring static routing can improve network performance , And it can guarantee bandwidth for important applications .
l Static routing can be done in VPN Use in instance , It is mainly used for VPN Routing management .
Examples of basic functions of configuring static routing
specifications : Apply to V200R002C01 And later versions 、 All forms AR Router .
Networking requirements : As shown in the figure , Hosts belonging to different network segments pass through several Router Connected to a , Static routing protocol is required , Realize interworking between any two hosts in different network segments .
