Abstract: The problem of being unable to run microBFD using an IPv6 address over any member links of a layer 2 LAG when the LAG is DOWN (and its IPv6 address becomes or is TENTATIVE), is solved by running DAD for the address configured for the microBFD once the individual link is in DISTRIBUTING or STANDBY state and triggering (or starting) microBFD once the DAD for that address completes successfully. Further, member links of the LAG may be permitted to continue running microBFD even if the LAG interface is DOWN and even if some other member links (but not all member links) of the LAG are DOWN.
