As a result of a known issue, TMM may respond to an ICMPv6 echo request using the auto-lasthop mechanism, when this has been disabled on the vlan.
Traffic may not follow the expected path.
- Auto-lasthop disabled on the ingress vlan - ICMPv6 echo request for a self-IP on the ingress vlan. - Route to the client IP address via a different vlan TMM may respond directly using the auto-lasthop feature and not via the route lookup.
None
TMM now correctly uses the configured option for auto-lashop and ICMPv6 traffic
