%Sep 7 09:01:31 2004 SwitchB IFNET/5/UPDOWN:Line protocol on the interface Vlan-interface2
turns into UP state
Perform the display interface tunnel 4 command on Switch A to identify the state of the primary LSP.
You can find that the tunnel interface is up.
About 5 seconds later, perform the display mpls lsp verbose command on Switch B. You can find
that Tunnel5 is still bound with interface VLAN-interface 2 and is unused.
7) Create a static route for routing MPLS TE tunnel traffic
[SwitchA] ip route-static 4.1.1.2 24 tunnel 4 preference 1
Perform the display ip routing-table command on Switch A. You can find 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.
Do the following:
z
Set up an MPLS TE tunnel to forward the VPN traffic from PE 1 to PE 2.
z
To allow the MPLS L3VPN traffic to travel the TE tunnel, configure a tunneling policy to use a
CR-LSP as the VPN tunnel when creating the VPN.
