[j-nsp] Vpls-ldp signaling

[Benny Sumitro]

Hi Steven,

I got it from the Junos 7.6 feature guide. 
http://www.juniper.net/products/junos/105026.pdf

So is it true?

Cheers,
Benny

I don't think this is correct. Would you mind to tell where did you get this info ?
All currently supported JUNOS releases do NOT support LDP based signaling for VPLS.

Regards,
Steven
