Hello everyone,
I am just trying to configure L2TPv3 over IPv4, but according to the doc it is supported only on 100G linecards. So now i am trying to run it over IPv6 on ASR9k between two A9ks according to the: https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-2/lxvpn/configuration/guide/b-l2vpn-cg-asr9000-62x/b-l2vpn-cg-asr9000-62x_chapter_0101.html#concept_E90BC873F0B148AAB62723CEB88FF159
! attachment circuit for test purposes
interface GigabitEthernet0/2/0/47.123 l2transport

pw-class l2tpv3_class
source <some-nonexisting-ipv6-address-as-required>

Now, when I start to generate traffic I can see it on the Bundle between ASRs. None of it however arrives at the AC subinterface and possibly not even on the remote pseudowire:
PW: neighbor <loopback>, PW ID 2000, state is up
PW class l2tpv3_class, XC ID 0x220000e
Encapsulation L2TPv3, protocol none

L2TP class not set, IPv6 source address <hidden>

Am I missing something? I do not see any drops in np counters and I am sending untagged traffic.
