I think you got confused with concepts of signaling protocol and lsp istelf.
mpls is foundation of all new technologies that rely on mpls label switching. but mpls lsp depends on signaling protocols such as rsvp or ldp for the label swapping. bgp is still the protocol that utilize the lsp (in the table inet.3). vpls can be implemented via either ldp based (martini) or bgp driven (kompella). --- On Fri, 7/8/09, Simon Chen <[email protected]> wrote: > From: Simon Chen <[email protected]> > Subject: Re: [j-nsp] lsp required for vpls? > To: "Harry Reynolds" <[email protected]> > Cc: "[email protected]" <[email protected]> > Received: Friday, 7 August, 2009, 5:09 AM > Thank you all for the reply. > > Do I need to explicitly configure MPLS LSPs between the PEs > (using > protocols/mpls/label-swithing-path)?
