We faced a problem with Cisco routers where it will have partial =
reachability over IPv6, in the same LAN. Looking further, We found that =
it was having problem with Neighbor solicitations.
The solution then was to remove the IPv6 configs from the interface and =
putting them back. This problem was quite unpredictable and we were =
unable to reproduce.
