Traffic forwarding

After an MPLS TE tunnel is established, traffic is not forwarded on the tunnel automatically. You must direct the traffic to the tunnel by creating a static route that reaches the destination through the tunnel interface.

This is the easiest way to implement MPLS TE tunnel forwarding. However, when the traffic to multiple networks is to be forwarded through the MPLS TE tunnel, you must configure multiple static routes, which are complicated to configure and difficult to maintain.
