[TECH] PPPoE server on ASR 920

Hi.

I need some help. I hope some of you are able to help me :)

I configured a pppoe server on a brand new asr 920 plateform (advanced
metro ip access) but it's not working.

My set up is trivial :

1/ Add a bba-group and a virtual template :

bba-group pppoe BBAPPPOE
 virtual-template 1
 sessions per-mac limit 2

interface Virtual-Template1
 ip unnumbered Loopback0
 no peer default ip address
 ppp authentication pap CPE_USER

2/ Then, configure the Radius :

aaa group server radius<removed>
 server<removed> auth-port 1812 acct-port 1813
 ip radius source-interface Loopback0
!
aaa authentication ppp CPE_USER group <removed>
aaa authorization network default group removed>

radius-server host<removed> auth-port 1812 acct-port 1813 key 7 <removed>

3/ Finally, I configured an interface accepting pppoe :

interface GigabitEthernet0/0/4
 description TEST-PPPOE
 no ip address
 media-type rj45
 negotiation auto
 pppoe enable group BBAPPPOE

A router, plugged on the interface Gi 0/0/4, is sending pado packets but
ASR920 is not seeing these packets :

Counters does not increment, debug says nothing.

ASR920-ALE-1#sh pppoe statistics

But I can see input packets with

ASR920-ALE-1# sh interfaces Gi 0/0/4

Has anyone have experience with  pppoe server on a ASR920 ?

Thanks a lot :)

Nicolas.
