How to import traffic to a TE tunnel on S series switches

For S series switches (except the S1700), use either of the following methods to import traffic to the TE tunnel:
- Configure static routes. For example, after you run the ip route-static 10.0.0.0 24 tunnel1/0/0 command, traffic destined for 10.0.0.0/8 is forwarded through Tunnel1/0/0.
- Configure auto routes in IGP shortcut mode. After the auto routes are configured in IGP shortcut mode, TE tunnels act as logical links to participate in IGP route calculation and tunnel interfaces are used as the outbound interfaces of the ingress routers, and do not affect the IGP route calculation by other routers.
