Open a support case requires a cisco service contract. In this free training video, liz cacic provides an overview of the mpls traffic engineering technology as it relates to the ccie exam. Pdf traffic engineering with constraint based routing in. With mpls, traffic engineering capabilities are integrated into layer 3, which optimizes the routing of ip traffic, given the constraints imposed by backbone capacity and topology.

The task of mapping traffic flows onto an existing physical topology to facilitate. Traffic engineering with mpls provides you with information on how to use mpls te and associated features to maximize network bandwidth. This example implements two dynamic tunnels automatically set up by the ingress label switch routers lsr and two tunnels that use explicit paths. Outer label used to routeswitch the mpls packets in the network last label in the stack is marked with eos bit allows building services such as mpls vpns traffic engineering and fast reroute vpns over traffic engineered core any transport over mpls label stacking te label ldp label vpn label inner label outer label ip header. Mpls configuration guide for cisco asr 9000 series routers. Mpls traffic engineering traffic protection using fast reroute. Mpls pointtomultipoint traffic engineering note thistechnologyisnotapplicablefortheciscoasr900rsp3module. This lsp gets carried inside a traffic engineering tunnel, so we can see this te label with the detail option or by looking for the te label the oldfashioned way with show mpls traffic eng tunnels tunnel 7 now p5 only looks at the top te label and acts.

Pdf in todaypsilas service provider networks mpls traffic engineering mpls te is one of the fastest growing implementation. This book focuses on realworld applications, from design scenarios to feature configurations to tools that can be used in managing and troubleshooting mpls te. Our example implements two dynamic tunnels automatically set up by the ingress label switch routers lsr and two tunnels that use explicit paths. Again, the label seen in the show mpls forwarding output is for the end to end lsp. Mpls traffic engineering per l2tpv3 about the author.

Mplste uses cspf to create a shortest path based on a series of constraints. The following additional informational resources are provided in this lesson. Pervrf mplste tunnels this is a solution to route traffic from different vrfs to different mplste tunnels rather than making all vrfs traffic to go through a single mplste tunnel. Mpls te provides an integrated approach to traffic engineering.
