Layer 3 Routing Commands 1548
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, Dell Networking 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, Dell Networking enables configuring a
static reject route for that network on the router. Such traffic is discarded and
an ICMP destination unreachable message is sent back to the source. Static
reject routes are typically used to prevent routing loops.
Default Routes
Dell Networking 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
(1).
