[cisco-bba] IPv6 PPPoE clients into VRF

I'm wondering if it's currently possible to insert a dual-stack IPv4/IPv6
PPPoE session into a VRF?


My setup is very straightforward with a fixed IPv4 address and stateless WAN
IPv6 address (no need to worry about LAN addressing at the moment).

I'd like to provision user's configuration through a RADIUS profile:


User-Name = "rado2 at shdsl"

        Framed-IP-Netmask =

        Framed-IP-Address =

        Cisco-AVPair = "ipv6:prefix#1=2a01:148:900:5::/64"

        Framed-Protocol = PPP

        Service-Type = Framed-User 


The VRF is configured on my testlab router as:


vrf definition ZZZ

 rd 100:100


 address-family ipv4

 route-target export 100:100

 route-target import 100:100



 address-family ipv6

 route-target export 100:100

 route-target import 100:100



interface Loopback200

 vrf forwarding ZZZ

 ip address

 ipv6 address 2A01:148:900:4::3/128



IOS used on the BRAS is: C7301-ADVIPSERVICESK9-M), Version 12.2(33)SRD4.

Device hardware is Cisco 7301.


We'd usually use the following RADIUS profile lines when configuring an IPv4
only customer, but that doesn't seem to work when the customer is a
dual-stack PPPoE session.



Cisco-AVPair = "lcp:interface-config#1=ip vrf forwarding ZZZ"

Cisco-AVPair = "lcp:interface-config#2=ip unnumbered Loopback200"


Thanks for you help!


Kind Regards,
