--- Comment #17 from benoitc <beno...@enki-multimedia.eu> --- (In reply to Zhenlei Huang from comment #15) So to give a better idea I have 4 machines plugged to this switch. 3 with a qlnxe card (<PREFIX>::11, <PREFIX>::12, <PREFIX>::13) and one with a mellanox card <PREFIX>::10 : |- ::11 machine A |- ::12 machine B SWITCH --|- ::13 machine C | |- ::10 machine D A, B, C can ping D on <PREFIX>::10, and D can ping A, B, C on their <PREFIX> . A, B, C can't ping each others using the global <PREFIX>. >>> A, B, C , D can ping each others using the local link IP `fe080::....` A, B, C, D can be pinged from an external machine (outside of the switch) and can ping other machines on internet using their <PREFIX> IP. I don't understand why A, B, C can't ping each others on <PREFX>::{11,12,13} while they can using the IPv6 local link `fe80::` and be reached from outside. Any idea what could be the issue? Maybe an option to set. Using Linux this is working perfectly and th eissue is not reproduced. -- You are receiving this mail because: You are the assignee for the bug.
