IP Unicast Commands
configure iproute add blackhole
configure iproute add blackhole <ip address> <mask>
Description
Adds a blackhole address to the routing table. All traffic destined for a configured blackhole IP address
is silently dropped, and no Internet Control Message Protocol (ICMP) message is generated.
Syntax Description
Default
N/A.
Usage Guidelines
A blackhole entry configures packets with a specified MAC destination address to be discarded.
Blackhole entries are useful as a security measure or in special circumstances where a specific
destination address must be discarded. Blackhole entries are treated like permanent entries in the event
of a switch reset or power off/on cycle. Blackhole entries are never aged out of the forwarding database
(FDB).
Example
The following command adds a blackhole address to the routing table for packets with a destination
address of 100.101.145.4:
configure iproute add blackhole 100.101.145.4
History
This command was available in ExtremeWare 2.0.
