A. Lindem and J. Arkko,

Some feedback on this draft. In section 5:

"5.  OSPFv3 Router ID Selection
A pseudo-random number SHOULD be used for the OSPFv3 Router ID."

I think it would be valuable to describe why a pseudo-random number should
be chosen. The [OSPFv3] document doesn't make any reference to selecting a
pseudo-random number, so it would be good to justify the reasoning.
Something along the lines of:
"The router id in OSPFv3 is a 32-bit value [OSPFv3]. As outlined in
[OSPFv3], a router running OSPFv3 may not have an IPv4 address to
automatically select as the router id. Since auto-configuration cannot
guarantee a unique router id as outlined in [OSPFv3], a pseudo-random
router id is the solution for OSPFv3 autoconfiguration to prevent router id
collision."



Also, there's a small formatting error. Section 7.2 and 7.4 are not marked
correctly as headers.


Regards,
Rama
