Example
The following example enables the forwarding of IPv6 Unicast datagrams:
switchxxxxxx(config)#
ipv6 unicast-routing
28.29 ipv6 unreachables
Use the ipv6 unreachables command in Interface Configuration mode to enable
the generation of Internet Control Message Protocol for IPv6 (ICMPv6)
unreachable messages for any packets arriving on a specified interface.
To prevent the generation of unreachable messages, use the no form of this
command.
Syntax
ipv6 unreachables
no ipv6 unreachables
Parameters
N/A.
Default Configuration
The sending of ICMP IPv6 unreachable messages is enabled.
Command Mode
Interface Configuration mode
User Guidelines
If the switch receives a Unicast packet destined for itself that uses a protocol it
does not recognize, it sends an ICMPv6 unreachable message to the source.
If the switch receives a datagram that it cannot deliver to its ultimate destination
because it knows of no route to the destination address, it replies to the originator
of that datagram with an ICMP host unreachable message.
