    IPv6 ping failing between two mellanox cards

    ramakris

      Hi,

      I am using Mellanox 100G cards. I want to set IPV6 address static and ping between 2 machines 100G - 100G Point to Point

      I am trying with link local address, but it is failing local ping also.

      I have gone through Mellanox IPv6 assignment, did not find any documentation to assign IPV6 address
