[j-nsp] lsp required for vpls?

[Simon Chen]

Hi all,

I read in the VPN configuration guide that LSPs between PEs are
required for VPLS. However, I am able to establish a VPLS setup using
LDP signalling, but without MPLS-LSP between PEs.

Does anyone know why? My guess is that LSP is only required if you're
going for the BGP signalling, but not required if you're doing LDP.
Can anyone clarify this?

Thanks.
