NUD- ipV6.

Hi,
 	Not useful for router-router link. However it is very useful for 
first-hop redundancy in data center environment - if you cannot implement 
VRRP for some reason.
 	Best Regards,

While quick failure detection protocols like BFD are already present to detect the liveliness of the neighbor, does the providers/operators find NUD to be useful?
