Dual-stack PPPoE on ios xe

Hello

Right now i'm using ASR1k as PPPoE concentrator for my clients. It's ipv4 only PPPoE sessions and I want to modify it, so it will be dual-stack ipv4/ipv6 sessions. So far I was able to issue /64 prefix for every session via dhcpv6 but the problem is that for ipv6 connectivity ASR must create additional route for every session that points /64 ipv6 subnet to correlating virtual interface. As far as I know command ipv6 dhcp iana-route-add responsible for this, but even if it's issued ASR does not create routes. Is there any workaround or am I doing something wrong? Creating two different sessions for ipv4 and ipv6 was already considered and it's not an option.

I'm runing ios xe 03.07.02.S

For reference:

interface Virtual-Template1

ip unnumbered TenGigabitEthernet0/2/0

ip access-group test-net in

ip access-group test-net out

Hi Artyom,

Try removing "ipv6 nd managed-config-flag" and see if it helps.
