1.1 Static Route Overview
Static route is the routing information that is designated by network administrator to the
routing table by means of commands. Unlike a dynamic route, it does not set up routing
table according to routing algorithm. In dynamic route configuration, routing information
of the entire Internet must be sent to a router. The router is hard to hold the load. In this
time, static routes can be used to solve the problem. Sometimes, use static route with
less configuration to avoid using dynamic route. However, in a routing environment where
there are multiple routers and paths, it is very complicated to configure static routes.
To generate a static unicast routing table, network administrator has to be familiar with the
network topology and configure it according to the actual routing requirements. In this way,
the routing action can be controlled accurately in network. The static routing table needs
to be reconfigured in time if the network topology is changed.
Static route is different from other dynamic routing protocol. Static route configuration
does not require that configure the related protocol data on interfaces. It only needs to
check the validity of static route parameters configured by users, but whether static route
configuration takes effect is still decided by the state changing of the corresponding egress
interface.
The following content is a routing table of ZXR10 5900E. Here, the administrator distance
of static route is 1.
