I've done a little bit of VLL/VPLS interoperability testing between 
Foundry and Juniper in the lab. Nothing especially complex, but haven't 
hit any "holy crap what were you people thinking" moments at any rate. One 
thing you don't want to do quite yet with Juniper's BGP/LDP support for 
VPLS is mix the two signaling types in the same mesh. I believe there are 
some enhancements for this coming up in JUNOS 9.0, but in the mean time 
you may not be able to "extend" your existing BGP signaled VPLS network 
with Foundry LDP signaled devices.
