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.

Create a static route for routing MPLS TE tunnel traffic:
[SwitchA] ip route-static 3.2.1.2 24 tunnel 0 preference 1
Execute the
display ip routing-table
command on Switch A. You can see a static route entry with
interface Tunnel0 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, making sure
that the maximum bandwidth of each link that the tunnel traverses is 10000 kbps.
