Enabling sending ICMPv6 destination unreachable
messages
About sending ICMPv6 destination unreachable messages
The device sends the source the following ICMPv6 destination unreachable messages:
• ICMPv6 No Route to Destination message—A packet to be forwarded does not match any
route.
• ICMPv6 Communication with Destination Administratively Prohibited message—An
administrative prohibition is preventing successful communication with the destination. This is
typically caused by a firewall or an ACL on the device.
• ICMPv6 Beyond Scope of Source Address message—The destination is beyond the scope
of the source IPv6 address. For example, a packet's source IPv6 address is a link-local address,
and its destination IPv6 address is a global unicast address.
• ICMPv6 Address Unreachable message—The device fails to resolve the link layer address
for the destination IPv6 address of a packet.
• ICMPv6 Port Unreachable message—No port process on the destination device exists for a
received UDP packet.
Restrictions and guidelines
An ICMPv6 destination unreachable message indicates that the destination is not reachable from the
source device. Attackers can launch malicious attacks to make the device generate incorrect
ICMPv6 destination unreachable messages, which will affect the function of the network. To protect
the network from malicious attacks and decrease unnecessary network traffic, you can disable the
sending of ICMPv6 destination unreachable messages.
