The 'blackhole' option in the 'ip route' command specifies that packets matching the destination route are silently discarded without sending an ICMP error notification to the sender. This means the switch will discard packets to the destined host without any additional notification.
C, blackhole option specifies that packets matching the destination route are silently discarded and no ICMP error notification is sent to the sender.
