COMMENT
I am having trouble reconciling 3.4.4 and 3.4.6.

3.4.4 seems to tell us how to handle the situation where both System-Id
and Router-Fingerprint are identical:

   If the fingerprints are identical in both content and length (and
   state of the S bit is identical) and the duplication is detected in
   hellos then the both routers MUST generate a new System ID and
   restart the protocol.

And then 3.4.6 says:

   Also note that the conditions for detecting duplicate System
   ID will NOT be satisfied because both the System ID and the Router-
   Fingerprint will be identical.

So, I am confused.


"entropy" is already a collective noun, so I think if you want to
pluralize it, you need to say "sources of entropy"


I am surprised that you are recommending HMAC-MD5, but I guess that's
how IS-IS rolls?
