Yes.  With this  RADIUS account (the prefix is statically configfured in
this case):

bjoermor at ipv6.online.no Cleartext-Password := verysecret
                Framed-Interface-Id := 0:0:0:c


I get this on the client side:


ipv6-pppoe-1:~# pppd nodetach debug noip call ipv6-1

And the expected ::c ifid is used both on the link local and the global
address:


ipv6-pppoe-1:~# ifconfig ppp0
ppp0      Link encap:Point-to-Point Protocol  
          inet6 addr: 2001:4600:10:11::c/64 Scope:Global
