[c-nsp] Assigning a static IPv6 address to a PPP session

Hello all

I am trying to test IPv6 configuration for PPPoE / DHCP-PD
termination. I have trouble assigning a "static" /128 IPv6 address
through radius.

I use the following simple config for the LNS

interface Virtual-Template100
 ip unnumbered Loopback4
 no ipv6 nd prefix framed-ipv6-prefix
 ipv6 enable
 ipv6 nd other-config-flag
 no ipv6 nd ra suppress
 ipv6 dhcp server LAN
 peer default ip address pool v4_POOL
 peer default ipv6 pool PPPOE
 ppp authentication chap
 ppp ipcp dns 10.0.1.1

ipv6 local pool PPPOE 2001:100::/64 128 shared
ipv6 local pool LAN 2001:200::/48 64

Using the Radius-Attribute Cisco-AVPair = "ipv6:prefix#1=2001:1::/64 0
0 onlink autoconfig" the router can statically define the prefix
assigned through the DHCP-PD to the CPE

I cannot find the appropriate Radius-Attribute for statically defining
the IPv6 address for the CPE's PPP interface.

Does anyone knows how to define through radius the IPv6 address that
can assigned to a PPP user?

Thanx for your help
