Mark,

> I don't think it is a Best current practice if router redundancy hasn't been considered or tested and deployed, and can therefore be documented. I see value in the approach because of SLAAC compatibility with hosts however I think it is currently half baked.

I don't understand either why the IESG thinks this should be a BCP.
But for different reasons.

Cheers,
Ole
