Usage guidelines
ICMPv6 Time Exceeded messages are sent to the source of IPv6 packets after the device discards IPv6
packets because hop or reassembly times out.
To prevent too many ICMPv6 error messages from affecting device performance, disable this function.
Even with the function disabled, the device still sends Fragment Reassembly Time Exceeded messages.
Examples
# Disable sending ICMPv6 Time Exceeded messages.

[Sysname] undo ipv6 hoplimit-expires enable
