I did find a bunch of editorial nits which I will send to the editor.
The following issues are more substantive:

Section 4.2:
>  Neighbor Unreachability Detection (NUD) ... is required for
multicast.

What does that mean?  You don't do NUD for multicast addresses.

4.6:
>   supporting multicast applications. A primary IPv6 multicast
>   application is Neighbor Discovery (all those solicited-node mcast

Neighbor Discovery is not an "application".  ND is a network-layer
function, not an application-layer function.  Suggest:
    supporting multicast protocols and applications.  A primary IPv6
    multicast protocol is Neighbor Discovery (all those solicited-node
    multicast

This needs to be resolved before this document is published as an RFC.
Making this document fully define router requirements would
significantly
delay publication (and this would certainly not be ready for last call).
Hence, I think this document should not document router requirements
at all, and leave that to a separate document.  That is, I would suggest
that section 9 be removed and put in a separate draft.

10:
>   Network Management, MAY be supported by IPv6 nodes.

What does this mean?  Does this specifically mean SNMP (if so say so).
If not, what is the purpose of this sentence?  It would basically be
saying "A node MAY support whatever configuration mechanism it
supports."
which seems odd to say.

Any MIBs in particular or just whatever the implementor wants?
For example are the MIBs mentioned in 10.1.1 and 10.1.2 SHOULDs or not?

12:
There's a lot of normative references to works in progress.
Will this hold up publication of this document until they're all RFCs?
If so, it might be good to see if some can turned into informative
references or removed.
