# Execute the display interface tunnel 4 command on Switch A to identify the state of the primary
LSP. You can see that the tunnel interface is up.
# About 5 seconds later, perform the display mpls lsp verbose command on Switch B. You can see
that Tunnel5 is still bound with interface VLAN-interface 2 and is unused.

MPLS TE in MPLS L3VPN configuration example
Network requirements
CE 1 and CE 2 belong to VPN 1. They are connected to the MPLS backbone through PE 1 and PE 2. The
IGP protocol running on the MPLS backbone is OSPF.
Set up an MPLS TE tunnel to forward traffic of VPN 1 from PE 1 to PE 2.
