RSVP-TE signaling on IOS XR
LDP and RSVP-TE are both signaling protocols used for establishing LSP in the MPLS networks. The latter one provides traffic engineering capability and in this article, I will try to set basic MPLS-TE tunnels on IOS XR devices to show you a problem, you can run into. A label switched path (LSP) is a sequence of LSR that switch a labeled packet through an MPLS network. As long LSP is contiguous (end-to-end between PE routers) there should be no problem in forwarding packets....
