Erik,
This paragraph talks about the requirements of the routing protocols,
not about the need for routers to move around:
Routing protocols running on a router may exhibit different
requirements for uniqueness of interface addresses; some have no such
requirements, others have requirements ranging from local uniqueness
only, to uniqueness within, at least, the routing domain (as defined
in [RFC1136]).
The only requirement I know if in the *routing protocols* is around
router ID uniqueness.
If you disagree, then can you please explain why there is a need to
refer to routing protocols in the above paragraph?
I can see why the text in the document may be confusing. But I think the
primary reason we require uniqueness is the one that I explained in the
previous e-mail. I would also like to point out that there are *some*
routing protocols that *do* require unique IDs -- I'm told that this is
the case with OLSR, for instance. So as far as I can tell the text is
factually correct, even though I do agree with you that for most routing
protocols its not the case.
