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.
[SwitchA] ip route-static 3.2.1.2 24 tunnel 0 preference 1
Perform the display ip routing-table command on Switch A. You can find 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 from Switch A to Switch D.
