3.3.1 Introduction to the Static Route
Static routes are routes which the administrator configures manually. Through the
configuration of static routes, you can build an interconnected network. Each static
route has one of the following properties, so there are three kinds of routes:
z
Reachable route: which is the case for common routes, that is, IP packets are sent
to the next hop along the route marked by the destination.
z
Destination unreachable route: When a static route to a destination has the
property of reject , any IP packet bound for it will be discarded, and the source will
be informed that the destination is unreachable.
z
Blackhole route: When a static route to a destination has the property of
blackhole , any IP packet bound for it will be discarded, and the source will not be
informed.
Among the properties, the reject and blackhole are commonly used to control the
range of destination that the XE IP PBX can reach and can help troubleshoot the
network.
3.3.2 Introduction to the Default Route
The default route is a special case of static route, which is used when no matched route
is found. In a routing table, a default route has a routing address/mask pair of
0.0.0.0/0.0.0.0. You can view the destination of a default route by running the display
ip routing-table command.
