In your previous mail you wrote:

   I have a question about RFC2472 - "IP Version 6 over PPP". The RFC talks
   about the negotiation of the Interface-Identifier and specifies the
   Interface-Identifier Configuration Option. In this case the upper 64 bits
   are just fe80::
   
=> yes, IPv6CP provides only configuration of link-local addresses
(for address/prefix/routing).

   It does not mention if there is any standard way to configure a
   global/site-local prefix on a point-to-point link i.e. are there
   configuration options to let one side tell the other about a global
   prefix?
   
=> no, this is done by auto-configuration if one end is a router
or by still to be defined protocol (i.e. manual configurtion but
look at last interim meeting proceeding where this was discussed)
if both ends are router. If no end is router, you don't need
more than link-local address...

   Or is it just left upto the users at both ends to decide on a prefix
   somehow and then configure it on each end?
   
=> this is the current standard solution for the router-to-router case.

   I'm sorry if there is an RFC about this that I missed...
   
=> RFC 2462 "IPv6 Stateless Address Autoconfiguration"
(note: on the router side, you can put the prefix configuration
in ipv6-up/ipv6-down scripts called when IPv6CP comes up or down.
This works very well, usually you even get a race between router
advertisement and solicitation so autoconf is always immediate).
