Arie,
Both boxes are on 15.2S with the exception of PE1 having the bootloader version of EY1 while PE2 is on EY2.
The issue I'm facing with VPLS is only happening when using BGP autodiscovery.
>From the output that I'm seeing on PE1, it is failing to establish a targeted LDP session with the PE2 lo0 next-hop router which the physical interface IP is correctly determined i.e. 200.28.9.246.
On PE2, it correctly detects PE1's next-hop router lo0.

Local interface: VFI ME002617 vfi up
Interworking type is Ethernet

Default path: no route
No adjacency

VC statistics:

transit byte totals: receive 0, send 0
transit packet drops: receive 0, seq error 0, send 0
Manual VPLS provisioning and EoMPLS work as advertised.
