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.
