[c-nsp] BGP Signalled VPLS

Thanks Nick,

Yeah I recall using no rd and no route targets with a vpls w/bd ad and ldp
sig.... must have all worked with some automagic rd and rt thingy's

Also my version of me3600 ios doesn't have bgp signaling possible, only ldp.
I think a previous poster (waris maybe) mentioned that 15.3(2)S or something
like that was required for bgp sig and that cisco is making a move towards
more support for bgp sig.

I was just exploring some of this in my me3600 with 15.2(4)S1.... 

What is the difference in the 2 following things... ?  l2 vfi and l2vpn
context vfi ?

Switch(config)#l2 vfi ?
  WORD  VFI name

Switch(config)#l2vpn vfi context vfi ?
  <cr>

Why would I use one over the other?

Aaron

Had a call with cisco tac and they managed to get it working by removing the
RD.

No idea why this resolved it.  Now to try and get it to working with a
juniper PE.
