NOTE:
On an MPLS TE tunnel configured using a static CR-LSP, traffic is forwarded directly based on label at the
transit nodes and egress node. Therefore, it is normal that the FEC field in the sample output is empty on
Switch B and Switch C.
7.
Create a static route for routing MPLS TE tunnel traffic.

Perform the display ip routing-table command on Switch A. You can see a static route entry with interface
Tunnel 0 as the outgoing interface.
MPLS TE using RSVP-TE configuration example
Network requirements
Switch A, Switch B, Switch C, and Switch D are running IS-IS and all of them are Level-2 devices.
Use RSVP-TE to create a TE tunnel with 2000 kbps of bandwidth from Switch A to Switch D, ensuring that
the maximum bandwidth of each link that the tunnel traverses is 10000 kbps.

Configuration procedure
1.
Assign IP addresses and masks to interfaces (see
) (details not shown)
2.
Enable IS-IS to advertise host routes with LSR IDs as destinations
