Thanks Robert Yes, a bit like L-LSP but within the TE domain -----Original Message----- From: Robert Raszuk [mailto:raszuk@cisco.com] Sent: 28 January 2002 16:12 To: LIAN Franklin FTLD/IAP Cc: Ruyter Hill; 'mpls-ops@mplsrc.com' Subject: Re: FW: Guaranteed QoS using MPLS? > by can put each VPN-LSP into individually configured MPLS-TE. That is pretty easy and available today at both cisco & juniper. What Ruyter is trying to acomplish is to separate traffic from any given VPN into multiple TE tunnels.
