Dell Static Reject Routes, Default Routes

966 IP Routing Commands
The addition of a preference option has a side benefit. The preference option
allows the operator to control the preference of individual static routes
relative to routes learned from other sources (such as OSPF). When routes
from different sources have the same preference, PowerConnect routing
prefers a static route over a dynamic route.
Static Reject Routes
To administratively control the traffic destined to a particular network so that
it is not forwarded through the router, PowerConnect enables configuring a
static reject route for that network on the router. Such traffic is discarded and
the ICMP destination unreachable message is sent back to the source. Static
reject routes are typically used to prevent routing loops.
Default Routes
PowerConnect routing provides a preference option for the configuration of
default routes. A configured default route is treated exactly like a static route.
Therefore, default routes and static routes have the same default preference.
