: Indicates a blackhole route. If a static route to a destination is marked with
blackhole
, the
outbound interface of this route is the Null 0 interface regardless of the next hop address, and all the IP
packet addresses destined for this destination are dropped without the source host being notified.
description text
: Provides a description for the current route, which is a string of 1 to 60 characters.
