Hi Everyone,
Would like to hear from you on the significance of IPV6 "Neighbor Unreachability detection (NUD)" specifically on the Router-Router link. 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?

Coming from an Alcatel address, presumably you're aiming for MEF-compliance? i.e. "Can it detect a dead neighbour in 50ms or under?" might be a better query.
I'd be interested to hear what people think, anyway.

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.
