5.1 IPv6 Static Route Overview
Static routes refer to the routes that the network administrator creates by using
configuration commands in the routing table. Static routing is different from dynamic
routing that creates a routing table according to the routing algorithm.
When dynamic routing is applied, sometimes it is necessary to send the routes of the
entire Internet to a router and then the router can hardly tolerate such a huge load. In that
case, static routing can be applied to solve the problem. With static routing, only a few
configurations are required to eliminate the use of dynamic routes.
In a routing environment involving multiple routers and multiple paths, however, it is rather
complex to configure static routes.
The static unicast routing table is configured by the network administrator according to
his/her routing requirements after he/she gets familiar with the entire network topology.
Therefore, the network administrator can exactly control routing behaviors in the network.
When the network topology changes, however, the network administrator needs to
reconfigure the static routing table.
Unlike dynamic routing protocols, static routing does not require the setting of protocol
data on the related interfaces but requires only the validity check of the user-configured
static routing parameters such as destination address, mask length, next hop and egress
interface. The validity of each configured static route, however, still depends on the status
of the egress interface.
