Hi Christian,

some comments from my side:
I'm not sure if we really need this encapsulation, as there are not many links layers left, but you 
should at least mention that it avoids some problems with switches dropping ISIS LSPs if it's 
encapsulated in IPv6

In my opinion you should also add to the IANA Considereations section that the allocation of the 
protocol number should be modified to something like "ISIS over IP" or only "ISIS", as it is a bit 
misleading that it's currently "ISIS over IPv4"

Also there should be at least some information about the coexistence of "standard" ISIS Routers 
and "ISIS over IPv6" routers. Example would be to allow only one ISIS encapsulation per interface 
and ignore the other (Router running ISIS over IPv6 with adjacencies would ignore standard ISIS 
PDUs and vice versa)
If you're not specifying it there arise problems with DIS routers.

Nit:
/of transmitted the PDUs/of transmitted PDUs/

Regards
Karsten Thomann
