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.
