%Sep 7 09:01:31 2004 SwitchB IFNET/5/UPDOWN:Line protocol on the interface
Vlan-interface2 turns into UP state
# 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 five seconds later, execute 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.

Create a static route for routing MPLS TE tunnel traffic:
[SwitchA] ip route-static 4.1.1.2 24 tunnel 4 preference 1
Execute the
display ip routing-table
command on Switch A. You can see a static route entry with
Tunnel4 as the outgoing interface.
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 respectively 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.
