[j-nsp] VPLS q-in-q

[Baldur Norddahl]

Hello

I got this working by changing VPLS encapsulation from tagged to raw and 
this config:

baldur at formervangen-edge1# show routing-instances poi-formervangen | 
display inheritance brief
protocols {
     vpls {
         encapsulation-type ethernet;
         ## 'no-control-word' was inherited from group 'POI-VPLS'
         no-control-word;
         ## 'mac-statistics' was inherited from group 'POI-VPLS'
         mac-statistics;
         mesh-group 1 {
             vpls-id 424;
             neighbor 10.9.124.0;
         }
     }
}
## 'vpls' was inherited from group 'POI-VPLS'
instance-type vpls;
vlan-id all;
interface xe-0/1/7.424;
interface ps1.0;
interface ps1.424; ## 'ps1.424' is not defined

[edit]
baldur at formervangen-edge1# show interfaces xe-0/1/7
flexible-vlan-tagging;
native-vlan-id 424;
encapsulation flexible-ethernet-services;
unit 424 {
     encapsulation vlan-vpls;
     vlan-tags outer 424 inner-range 1-4000;
}


I now get double tagged frames out on interface xe-0/1/7:

10:29:34.667573 00:22:07:4d:7b:0d > ff:ff:ff:ff:ff:ff, ethertype 802.1Q 
(0x8100), length 350: vlan 424, p 0, ethertype 802.1Q, vlan 201, p 0, 
ethertype IPv4, 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request 
from 00:22:07:4d:7b:0d, length 300

However I also need this on a 'ps' interface to support auto 
configuration with subscriber management. I tried replicating the 
configuration from xe-0/1/7.424 on ps1.424 and that configuration is 
accepted by the router but does nothing. Auto configuration does query 
the radius server. I then tried ethernet-vpls on ps1.0 which works but 
now I am missing the outer vlan tag.

baldur at formervangen-edge1# show interfaces ps1
apply-groups AUTO-PS;
encapsulation flexible-ethernet-services;
unit 0 {
     encapsulation ethernet-vpls;
}
inactive: unit 424 {
     encapsulation vlan-vpls;
     vlan-tags outer 424 inner-range 1-4000;
}

Packet counters on ps1.424 is counting output packages but 
auto-configure is not triggered.

Is there a trick to get the full q-in-q double tagged headers back in 
this case?

Thanks,

Baldur
