Static routes
USER GUIDE
147
In the same way the command:
set route host 10.1.10.10 dev null0
blocks traffic towards host 10.1.10.10.
The ip command, gives the possibility to specify routes such as: blackhole, prohibit and
unreachable. For example:
ip route add blackhole 1.1.1.1
ip route add prohibit 2.2.2.2
ip route add unreachable 3.3.3.3
Using blackhole parameter, outgoing packets will be rejected, as for null0 route.
Using prohibit parameter, packets will be rejected but a Prohibit ICMP packet will be sent to the IP
source.
Using unreachable parameter, packets will be rejected but an Unreachable ICMP packet will be
sent to the IP source.
DISPLAYING STATIC ROUTES
The static routes configured can be displayed using the following command:
show ip route
For example:
root@IMOLA> show ip route
Router# show ip route
