The HP FlexFabric Switch must configure the maximum hop limit value to at least 32.
The Neighbor Discovery protocol allows a hop limit value to be advertised by routers in a Router Advertisement message to be used by hosts instead of the standardized default value. If a very small value was configured and advertised to hosts on the LAN segment, communications would fail due to the hop limit reaching zero before the packets sent by a host reached their destination.
If the max hop set is not configured then use the following command to configure it: [HP] ipv6 hop-limit 255
Review the HP FlexFabric Switch configuration to determine if the maximum hop limit has been configured. If the maximum hop limit is not configured, this is a finding. If it has been configured, then it must be set to at least 32; otherwise this is a finding.
