[j-nsp] Problem with VPLS and J-series routers

[Tomasz Klicki]

Hi there,
I'm trying to configure VPLS between two J2320 routers (Junos 9.5R2.7).
Topology looks like this:

PC1 (tagged vlan) --- J1 --- J2 --- J3 --- J4 --- PC2 (tagged vlan)

..but as you may presume not everything works correct.

Output from 'show vpls connections' on J1:

root at J1> show vpls connections
Instance: vpls1
  VPLS-id: 100
    Neighbor                  Type  St     Time last up          # Up trans
    192.168.5.4(vpls-id 100)  rmt   Up     Jul 23 19:17:06 2009           1
      Remote PE: 192.168.5.4, Negotiated control-word: No
      Incoming label: 262145, Outgoing label: 262145
      Local interface: lsi.1049344, Status: Up, Encapsulation: ETHERNET
        Description: Intf - vpls vpls1 neighbor 192.168.5.4 vpls-id 100

Looks good, but no packet is passing from PC1 to PC2. Can anyone tell me
what I do wrong? I'm not sure about configuration of encapsulation of
access ports for PC1 and PC2. Interface lsi.1049344 also looks strange
to me, it has no input/output packets:
