ipv6 routing-header-type0 deny
Configures IPv6 routing header Type 0 packet handling in hardware (fast-path) and kernel (slow-path).
Syntax
[no] ipv6 routing-header-type0 deny fast-path [slow-path]
Parameters
fast-pathDeny IPv6 routing header Type 0 packets in the hardware.
slow-pathDeny IPv6 routing header Type 0 packets in hardware and kernel.
Defaults IPv6 routing header Type 0 packets in the hardware are denied.
Command Mode GLOBAL CONFIGURATION

Usage
Information
Use the no version of this command to permit IPv6 routing header Type 0 packets. When configured to
permit IPv6 routing header Type 0 packets, OS10 allows normal switching and routing of packets with
IPv6 routing header Type 0. However, OS10 switches are compliant with RFC 5095 and drops any IPv6
routing header Type 0 packets that are destined to it.
Example:
Configure IPv6
RH0 deny in
hardware
OS10(config)# ipv6 routing-header-type0 deny fast-path

ipv6 unreachables
Enables generating error messages on an interface for IPv6 packets with unreachable destinations.
Syntax
ipv6 unreachables
Parameters None
Defaults ICMPv6 unreachable messages are not sent.
Command Mode INTERFACE
Usage
Information
By default, when no matching entry for an IPv6 route is found in the IPv6 routing table, the packet
drops and no error message is sent. Use this command to enable sending an IPv6 destination
unreachable error message to the source without dropping the packet.
The no version of this command disables generating unreachable destination messages.
