Re: 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.

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. :)
