configure iproute delete blackhole ipv6 default

configure iproute delete blackhole ipv6 default {vr vr_name}


Deletes a default blackhole route from the routing table.

Syntax Description

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.

Usage Guidelines

While a default route is for forwarding traffic destined to an unknown IPv6 destination, and a blackhole route is for discarding traffic destined to a specified IPv6 destination, a default blackhole route is for discarding traffic to the unknown IPv6 destination.

Using this command, all traffic with an unknown destination is discarded.

The default blackhole route is treated like a permanent entry in the event of a switch reset or power off/on cycle. The default blackhole route's origin is "b" or "blackhole" and the gateway IPv6 address for this route is "::."


The following example deletes a blackhole default route from the routing table:

configure iproute delete blackhole default


This command was first available in ExtremeXOS 10.1.

Platform Availability

This command is available on the platforms listed for the IPv6 unicast routing feature in the ExtremeXOS and Switch Engine 31.7 Feature License Requirements document.
