I know to little to nothing about IS-IS (the little bit I do know is 
that IS-IS = 0! :-), but I don't see how this is supposed to work.

How can a router that doesn't know anything about IPv6 make a forwarding 
decision for ("route") packets (datagrams) using an addressing system it 
knows nothing about? Since this router knows nothing about IPv6, how 
does IS-IS update the routing table with those 128-bit addresses (see 
also blivet[1])?

And if this is an ethernet network, I'd expect a non-IPv6 router (and 
any other non-IPv6layer 3 device) to discard any frames it receives with 
an ethertype of 86DD.
