Deletes a blackhole route from the routing table.
| ipv6Netmask | Specifies an IPv6 address/prefix length. |
| vr_name | Specifies the VR or VRF from which the route is deleted. |
If you do not specify a VR or VRF, the current VR context is used.
A blackhole entry directs packets with a specified 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.
The following example deletes a blackhole route from the routing table for packets with a destination address of 2001:db8::3452, so the packets are no longer discarded:
configure iproute delete blackhole 2001:db8::3452/128
