--- Comment #10 from Zhenlei Huang <zlei.hu...@gmail.com> --- (In reply to benoitc from comment #8) Sorry for late response. I'm lost in lots of mails. > I will try, so just changing the mtu using ifconfif ? Yes and no. Steps on node1: 1. ifconfig ql0 inet6 -ifdisabled # Turns on IPv6 Link-Local address 2. ifconfig ql0 mtu 4000 3. ifconfig ql0 mtu 1500 # Optionally (Mandatory if the switch does not support or is configured with jumbo frame) Repeat the above steps on node2. Then ping6 from node1 to node2 with IPv6 Link-Local addresses. -- You are receiving this mail because: You are the assignee for the bug.
