Forwarding Traffic onto MPLS TE Tunnels

Creating a TE tunnel and having it operational is one thing. Making sure that it is used to forward traffic is another. You can enable the TE tunnel to forward traffic in six ways:

  • Static routing

  • Policy-based routing

  • Autoroute announce

  • Forwarding adjacency

  • Direct mapping of AToM traffic onto TE tunnels

  • Class-based tunnel selection

Static Routing

A straightforward and simple way to send traffic into the TE tunnel is to configure a static route on the tunnel head end router. You just have to configure the TE tunnel as the outgoing interface in the static route. See Example 8-22 for the configuration.
